mysql.proc has gone corrupt. How can I fix it?

- by Metalcoder

I have a server running Debian 5.0, and MySQL. Suddendly, MySQL stopped working, and after many attempts to fix it, I decided to reinstall it. I installed MySQL 5.1.63, and when started it goes to safe mode. I made some typing, and when I executed mysql_upgrade as root, it complained: ... Running 'mysql_fix_privilege_tables'... ERROR 1548 (HY000) at line 1111: Cannot load from mysql.proc. The table is probably corrupted ERROR 1064 (42000) at line 1112: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'sqlstate 'HY000' set message_text='Unexpected content found in the performance_s' at line 1 ERROR 1548 (HY000) at line 1125: Cannot load from mysql.proc.

I also tried do check and repair the mysql.proc table, but got no success.

Apache2 config problem

- by Hellnar

For using my Debian VPS for multiple domains , I did such actions: removed the default one from sites-enabled/ and sites-available/ (config and the symbolic link) and I added this under sites-available/www.mysite.com : <VirtualHost MYIP:80> ServerName mysite.com ServerAlias www.mysite.com Alias /media/ /home/myuser/mysite/media/ Alias /admin_media/ /home/myuser/django/Django-1.2/django/contrib/admin/media/ WSGIScriptAlias / /home/myuser/mysite/wsgi.py ErrorLog /home/myuser/mysite/logs/error.log CustomLog /home/myuser/mysite/logs/access.log combined </VirtualHost> And I have changed my ports.conf to: NameVirtualHost MYIP:80 Listen 80 <IfModule mod_ssl.c> # SSL name based virtual hosts are not yet supported, therefore no # NameVirtualHost statement here Listen 443 </IfModule> Lastly I enabled the new domain via the command: a2ensite www.mysite.com After restart I get this error: myuser:~# /etc/init.d/apache2 restart Restarting web server: apache2apache2: Syntax error on line 281 of /etc/apache2/apache2.conf: Syntax error on line 1 of /etc/apache2/sites-enabled/www.birertek.com: /etc/apache2/sites-enabled/www.birertek.com:1: <VirtualHost> was not closed. failed!

Windows Scheduled Startup Task doesn't appear to be fully working but why?

- by Devtron

I originally tried to use Group Policy to enforce a startup script to run at startup. My startup script is a .CMD file, which calls 10 .exe files. Using Group Policy I could never get this to work....so I looked into using Scheduled Tasks. And here I am. I have tried two different versions of my script (for syntax purposes). I originally thought my syntax could be bad, so I tried a few approaches. Neither work. My #1 .CMD file approach commands look similar to this: start "this is my title" /D "C:\Somepathhere\myExecutable.exe" "..\..\published\wc_task.wfc" My #2 .CMD file approach commands look similar to this (it invokes a shortcut file): rundll32 shell32.dll,ShellExec_RunDLL "C:\Somepathhere\bin\Virtual Workflow.lnk" ^ Both of these scripts work fine if I manually run them, either by running the .CMD file, or even by manually forcing the Schedule Task MSC console to "Run" this script. Manual process seems to work fine, but automated it does not. My scheduled task is set for startup and uses "highest privileges" to execute as Admin. At the end of my .CMD script, I added a line to write to a text file, just to prove that the script was being run. That command looks like this: echo foo > C:\foo.txt When I reboot my server, and Schedule Tasks kicks in, I never get my ten .EXE files to run, but I do get the C:\foo.txt on my drive. What gives?

Please, help writing a MIB

- by facha

I have a problem with an snmpwalk query returning snmp variables in a non-uniform way: .1.3.6.1.2.1.10.127.1.3.3.1.2.215 -> Hex-STRING: 24 37 4C 0C 65 0E .1.3.6.1.2.1.10.127.1.3.3.1.2.216 -> Hex-STRING: 24 37 4C 0B A2 DA .1.3.6.1.2.1.10.127.1.3.3.1.2.217 -> STRING: "$7L f:" .1.3.6.1.2.1.10.127.1.3.3.1.2.218 -> STRING: "$7L k2" As you can see, some variables are of a STRING type, others are Hex-STRING. So, I'm trying to write a simple MIB to force them all come out as Hex-STRING. This is where I've gotten so far: TEST-MIB DEFINITIONS ::= BEGIN PhysAddress ::= TEXTUAL-CONVENTION DISPLAY-HINT "1x:" STATUS current SYNTAX OCTET STRING test OBJECT-TYPE SYNTAX PhysAddresss MAX-ACCESS read-only STATUS current ::= { 1 3 6 1 2 1 10 127 1 3 3 1 2 } END However, snmpwalk doesn't seem to notice my textual convention (even though the "test" variable is being recognized). I still get a mixture of STIRNGs and Hex-STRINGs. Could anybody point to where is my mistake? snmpwalk -v2c -cpublic 192.168.1.2 TEST-MIB::test ... TEST-MIB::test.216 = Hex-STRING: 24 37 4C 0B A2 DA TEST-MIB::test.217 = STRING: "$7L f:"

Search for files after a relative date using Windows search

- by Zoredache

I am looking for a way to save a search that includes a relative date. Specifically I am looking for a way to save a search that matches files that have a modification date that is 7 days ago. I have read the Windows Search Advanced Query Syntax document and I am not seeing a way to say 7 days ago. The numbers and ranges section does mention that relative dates are possible. The problem is that the relative dates described there do not fit the criteria I need. The lastweek almost looks like what I want except if I run a query like after:lastweek on a Monday it will only show my file that have been modified since Sunday at 12:00. The lastweek/lastmonth seem to relative to the start of the week/month which is not what I need. Multi-word relative dates: week, next month, last week, past month, or coming year. The values can also be entered contracted, as follows: thisweek, nextmonth, lastweek, pastmonth, comingyear. One nice thing about saved searches is that they are stored as an XML document and the file format is documented. I am not seeing how to form a correct value for a datetime. If I was able to understand this format, I suspect I could use a text editor and created a saved search that does what I want. Fragment from the examples: <conditions> <condition type="leafCondition" valuetype="System.StructuredQueryType.DateTime" property="System.DateModified" operator="imp" value="R00UUUUUUUUZZXD-30NU" propertyType="wstr" /> </conditions> To summarize I am looking for an answer to one or both of these questions How do I make a query for '7 days ago' using the standard syntax? How is the DateTime stored in a saved search?

PsExec and Remote Environment Variables, Logging, Etc.

- by alharaka

When I run PsExec on a remote computer, I always fall short of what I want. What I would like ideally in most situations is a) a log on an admin server where each individual log has the name of each the remote computer it was generated from (e.g. COMPNAME1.log, COMPNAME2.log, etc.) or b) a log file on each remote computer with whatever name I specify. When I try scenario (a), I use the following command. %SystemDrive%\path\to\psexec.exe @listofcomputers.txt -u DOMAIN\username cmd /c echo TEST >> \\server.company.tld\share\%computername%.log Problem is that it never works. All the computers just write to the log where %computername% is just the computer I execute PsExec from in my office. What I want are unique logs for each computer specific in the listofcomputers.txt that will correctly use the hostname from the remote environment variable without issue. Is that even possible? It does not seem to work for me. I tried this, and the syntax is clearly wrong. %SystemDrive%\path\to\psexec.exe @listofcomputers.txt -u DOMAIN\username "cmd /c echo TEST >> \\server.company.tld\share\%computername%.log" PsExec just fails saying the system file cannot be found (read: syntax fail). As for scenario (b), it appears to be a variation of a similar problem. When I run a command like this, it does not work. %SystemDrive%\path\to\psexec.exe @listofcomputers.txt -u DOMAIN\username "cmd /c echo %computername% >> \\server.company.tld\share\aggregated.log" Is there something I do not understand about remote path and environment variables with PsExec on the cmd.exe console (I have not even tried the dreaded PowerShell yet). I know such things work in a batch file (cmd /c \\server.company.tld\share\runthis.bat), but is there a reason it will not work when executing commands as arguments? I always need this, and can never get it!

Sporadic crash of master-slave MySQL replication process

- by obarshay

Hello, I was wondering if someone has experienced this and can perhaps provide some insight into this issue. We have a plan-vanilla MySQL master-slave replication set up. The tables are MyISAM and the master can get quite read/write active. We use the slave instance to perform full daily backups in order to avoid bringing down the master server. The backup process does the following: STOP SLAVE SQL_THREAD mysqlhotcopy all tables START SLAVE SQL_THREAD Every once in a while (once a month or so) the replication breaks with varying error messages indicating a corrupt query or log file. Here's one that happened last night: mysql> show slave status \G *************************** 1. row *************************** Slave_IO_State: Waiting for master to send event Master_Host: server8.propreports.com Master_User: nexus8 Master_Port: 3306 Connect_Retry: 60 Master_Log_File: bin.000045 Read_Master_Log_Pos: 581644327 Relay_Log_File: relay.000086 Relay_Log_Pos: 94131 Relay_Master_Log_File: bin.000045 Slave_IO_Running: Yes Slave_SQL_Running: No Replicate_Do_DB: Replicate_Ignore_DB: Replicate_Do_Table: Replicate_Ignore_Table: Replicate_Wild_Do_Table: Replicate_Wild_Ignore_Table: Last_Errno: 1064 Last_Error: Error 'You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '138070603'£' at line 1' on query.

Any advice on how to resolve this would be greatly appreciated.

How can I have puppet deploy ssh keys for virtual users?

- by Pheezy

I am trying to get puppet to assign authorized ssh keys for virtual users but I keep getting the following error: err: Could not retrieve catalog: Could not parse for environment production: Syntax error at 'user'; expected '}' at /etc/puppet/modules/users/manifests/ssh_authorized_keys.pp:9 I believe my configuration are correct (listed below) but is there a syntax error or scoping issue I am missing? I would simply like to assign users to nodes and have those users automagically have their ssh keys installed. Is there maybe a better way to do this and I'm just overthinking it? # /etc/puppet/modules/users/virtual.pp class user::virtual { @user { "user": home => "/home/user", ensure => "present", groups => ["root","wheel"], uid => "8001", password => "SCRAMBLED", comment => "User", shell => "/bin/bash", managehome => "true", } # /etc/puppet/modules/users/manifests/ssh_authorized_keys.pp ssh_authorized_key { "user": ensure => "present", type => "ssh-dss", key => "AAAAB....", user => "user", } # /etc/puppet/modules/users/init.pp import "users.pp" import "ssh_authorized_keys.pp" class user::ops inherits user::virtual { realize( User["user"], ) } # /etc/puppet/manifests/modules.pp import "sudo" import "users" # /etc/puppet/manifests/nodes.pp node basenode { include sudo } node 'testbox' inherits basenode { include user::ops } # /etc/puppet/manifests/site.pp import "modules" import "nodes" # The filebucket option allows for file backups to the server filebucket { main: server => 'puppet' } # Set global defaults - including backing up all files to the main filebucket and adds a global path File { backup => main } Exec { path => "/usr/bin:/usr/sbin/:/bin:/sbin" }

ssh use with netcat to forward connections via bastion host to inside machine

- by Registered User

Hi, I am having a server in a corporate data centre who's sys admin is me. There are some virtual machines running on it.The main server is accessible from internet via SSH. There are some people who within the lan access the virtual machines whose IPs on LAN are 192.168.1.1 192.168.1.2 192.168.1.3 192.168.1.4 the main machine which is a bastion host for internet has IP 192.168.1.50 and only I have access to it. I have to give people on internet the access to the internal machines whose IP I mentioned above.I know tunnel is a good way but the people are fairly non technical and do not want to get into a tunnel etc jargons.So I came across a solution as explained on this link On the gateway machine which is 192.168.1.50 in the .ssh/config file I add following Host securehost.example.com ProxyCommand ssh [email protected] nc %h %p Now my question is do I need to create separate accounts on the bastion host (gateway) to those users who can SSH to the inside machines and in each of the users .ssh/config I need to make the above entry or where exactly I put the .ssh/config on the gateway. Also ssh [email protected] where user1 exists only on inside machine 192.168.1.1 and not on the gateway is that right syntax? Because the internal machines are accessilbe to outside world as site1.example.com site2.example.com site3.example.com site4.example.com But SSH is only for example.com and only one user.So How should I go for .ssh/config 1) What is the correct syntax for ProxyCommand on gateway's .ssh/config should I use ProxyCommand ssh [email protected] nc %h %p or I should use ProxyCommand ssh [email protected] in nc %h %p 2) Should I create new user accounts on gateway or adding them in AllowedUsers on ssh_config is sufficient?

Apache 2 Fails to Start After Upgrade with No Errors

- by Mark Davidson

Hi all Hoping someone can help me with a server issue. Recently we upgraded to the latest apache on 2 boxes within are organisation. One being the master box the other being for failover. The upgrade went fine on the master box but on the failover box apache fails to start with no errors, being output or logged. Both boxes have the exact same configuration so found this a bit strange. I've reinstalled apache and have been through checking the configs and did not find any obvious errors. Eventally I ran a syntax check on each config file being included and found that one of the files apparently has syntax errors. Invalid command 'Order', perhaps misspelled or defined by a module not included in the server configuration Invalid command 'php_value', perhaps misspelled or defined by a module not included in the server configuration Invalid command 'GeoIPEnable', perhaps misspelled or defined by a module not included in the server configuration I've trippled checked all the modules are enabled but it still fails. I've googled the subject of these errors loads but have been unable to fine a solution. I was wondering if anyone had encountered such a problem before and could point me towards a solution. Thanks for your help in advance.

How to link to a subfolder of a share?

- by Nicolas Raoul

On my Windows XP server, a folder called Share2 is shared. It contains a subfolder called folder3. The guest account is protected by a password, which means network users have to type the guest password to access it. When a user types \\server\Share2 in his file explorer, he is prompted for a password. When a user types \\server\Share2\folder3 in his file explorer, an error appears. He is not even prompted for a password. This is problematic because I want to link to this particular folder. How can I link to folder3? Notes: - Both Desktop shortcuts and HTML links in IE7/8 give an error if I link to folder3, but work if I just link to Share2. - Using the file:// syntax instead of the \\ syntax leads to the same results. - Password setting per http://www.lancelhoff.com/how-to-password-protect-a-shared-folder - Not using "Simple File Sharing" - The error message is ???????????????????????? which means "could not find it. check the path and try again". No English Windows around to try, sorry! It is easy to reproduce the problem though, so can anyone post the English error message for the sake of searchability? Thanks!

What file transfer protocols can be used for PXE booting besides TFTP?

- by Stefan Lasiewski

According to ISC's dhcpd manpage: The filename statement filename "filename"; The filename statement can be used to specify the name of the initial boot file which is to be loaded by a client. The filename should be a filename recognizable to whatever file transfer protocol the client can be expected to use to load the file. My questions are: What file transfer protocols, besides tftp, are available to load the file (e.g. What protocols "can be expected to" load the file)? How can I tell? Can I see a list of these protocols? Does my choice of DHCP server influence which file transfer protocols are in use? Pretend I want to use dnsmasq instead of ISC's dhcpd Are these features dependent on the PXE which is in use (e.g. My Intel NICs use an Intel ROM)? I know that some PXE-variants, such as iPXE/gPXE/Etherboot, can also load files over HTTP. However, the PXE rom needs to be replaced with the iPXE image, either by chainloading or by burning the PXE rom onto the NIC. For example, the iPXE Howto "Using ISC dhcpd" says: ISC dhcpd is configured using the file /etc/dhcpd.conf. You can instruct iPXE to boot using the filename directive: filename "pxelinux.0"; or filename "http://boot.ipxe.org/demo/boot.php";

fedora, dhcpd fails to start

- by soxs060389

History: I got a tiny shiny plugserver which I want to plug to my ADSL router (or however you want to call it) on one end (eth0), and the other end (eth1) I want to run a dhcp server for my LAN. ATM I am stuck with getting LAN to work. OS is fedora 12. I configured my /etc/dhcp/dhcpd.conf like this: # # DHCP Server Configuration file. # see /usr/share/doc/dhcp*/dhcpd.conf.sample # see 'man 5 dhcpd.conf' # option domain-name "unknown.org"; option domain-name-servers 192.168.44.1; option subnet-mask 255.255.255.0; option broadcast-address 192.168.44.255; default-lease-time 86400; max-lease-time 172800; subnet 192.168.44.0 netmask 255.255.255.0 { host fedorabigbox { hardware ethernet 00:19:66:8E:61:74; fixed-address 192.168.44.21; } #host mobile #{ # hardware ethernet ***; # fixed-address 192.168.44.22; #} range 192.168.44.100 192.168.44.110; option routers 192.168.44.1; } # this is just dummy, as read many howtos, some suggesting to add a subnet blah netmask blah for each interface subnet 192.168.33.0 netmask 255.255.255.0 { range 192.168.33.100 192.168.33.110; option routers 192.168.33.1; } But the server fails to start when trying to start it via /etc/init.d/dhcpd start In general it would be nice if someone can point me to a in detail explanation of how network works, I am pretty new to this stuff. More concrete question: How to point the subnets to eth1 and the other to eth0, how can this be achieved? Does someone see any errors or flaws? Syntax should be correct, allready checked that with the dhcpd syntax check. Thanks for any help

What does this example bash startup script do?

- by Dimitri

I am trying to set up GNU Octave on my computer (Mac OS X 10.7.4). I am newbie in using Terminal and I need help to understand what the following script actually does: if [ -f ~/.bashrc ];then<br>        . ~/.bashrc<br> fi<br> PATH=$PATH:/usr/local/bin<br> BASH_ENV=~/.bashrc<br> export BASH_ENV PATH<br> export GNUTERM=aqua<br> alias octave="/Applications/Octave.app/Contents/Resources/bin/octave"<br> alias gnuplot="/Applications/Gnuplot.app/Contents/Resources/bin/gnuplot"<br> (taken from here: http://wikibox.stanford.edu/me112/index.php/Main/OctaveMatlabNotes) So this script begins with the simple conditional if statement. I don't understand the conditional expression - what is -f and .bashrc? What the statement . ~/.bashrc actually does? Then 2 variables are defined PATH and BASH_ENV. Why are they exported? Why GNUTERM=aqua is exported even if it's not defined anywhere? All I need is a script that would allow me to run Octave by simply typing octave in the terminal. I don't need an alias for the gnu plot. Thanks

auto-mounting shared folders in VirtualBox

- by brannerchinese

I am writing to ask what the effect of the auto-mounting process is in VirtualBox, and where the folders can be accessed within a guest Linux system if auto-mount is used. I have VirtualBox 4.0.4 installed on Mac OS 10.6.7, with Guest Additions apparently running correctly. The guest OS is Ubuntu 10.04, and I observe no apparent problems with it. I find that if the shared folders have "auto-mount" unchecked in the VirtualBox settings, they can then be mounted using the prescribed syntax sudo mount -t vboxsf folder_name path_to_mount_point and all works as it is supposed to. But if the auto-mount option is checked, then I find that I can no longer mount the shared folders manually. I get the error mounting failed with the error: Invalid argument and the folders also do not appear to mount anywhere else accessible to me. Using the syntax sudo mount -t vboxsf without specifying a path installs them in /media, with their names prefixed with sf_, but they are not easily accessible there and I have not been able to change their owner using chown, either. Thanks for your patient explanation.

How do you use VIM to edit tabular data (tables)? Specifically, BIND (named) DNS db files.

- by Richard Bronosky

I'm usually a purist when it comes to vimming. I don't like remapping keys, or learning to rely on a bunch of plugins. I like to feel just as powerful on foreign boxen as I do on my own dev box. I do, however, believe in syntax files. Even though the solution may not be a syntax file (bindzone.vim is what I use), I want it bad enough to do whatever. I regularly view or edit tab (or comma, but that would be a bonus) delimited data. I hate having to set my tabstop to some ridiculous number in order to have everything line up. Example: The BIND zone files are ~40+,6,2,5,15+. So, even though I could view them on a single screen, if I set ts=40, I cannot. I have been searching for a "dynamic tab size" solution for years, but no luck. I hate that my only good way of editing or even visualizing tabular data is to scp it to my work station and open it in Open Office. There has to be a better way.

When ran as a scheduled task, cannot save an Excel workbook when using Excel.Application COM object in PowerShell

- by Daniel Richnak

I'm having an issue where I've automated creating an Excel.Application COM object, add some data into a workbook, and then saving the document as an xlsx. This works fine if: I'm already in Powershell interactive host and either run each command in sequence, or execute as a ps1. I run it from cmd.exe, using the syntax: powershell.exe -command "c:\path\to\powershellscript.ps1" I create a scheduled task in Windows 7 / Server 2008 R2, use the above powershell.exe -command syntax, and use the mode "Run only when the user is logged on". It fails when I modify the same scheduled task, but set it to "run whether the user is logged on or not". Here's a sample script that illustrates the problem I'm having: $Excel = New-Object -Com Excel.Application $Excelworkbook = $Excel.Workbooks.Add() $excelworkbook.saveas("C:\temp\test.xlsx") $excelworkbook.close() I have a theory that the COM object fails somehow if my profile isn't loaded / if it's not performed in a command window. Any ideas on which options to choose when creating the scheduled task, or which options to use when creating the Excel object or using the SaveAs() function? Can anybody reproduce this? I've been able to see this behavior on both a Server 2008 R2 machine, and Windows 7. Haven't tried other platforms.

Why is the `remove rows` button not always present in MySQL Workbench?

- by Shawn

I'm using MySQL Workbench to remove rows from a table in my database. Most of the time, I will simply write a select statement, then select the rows I want to erase and use the remove rows button (circled in the screenshot below). But sometimes (quite often actually), the remove rows button does not appear. Instead, I get something like the screenshot below: The remove rows button is not there and the remove rows option is grayed out in the context menu, so basically, I can't remove rows... The only way I've found of solving this issue is to run the select query many times until the button appears (it usually does after 3 of 4 times). Does anyone know why this is happening? UPDATE Today, I've been running a select query dozens of times and the button never appears. It seems my incomprehensible workaround no longer works... Help! btw: Using a delete statement does work, though I would rather not have to write one for each row I want to remove as this happens quite frequently during development...

Can I use @import to import Kod's default style sheet into my own?

- by Thomas Upton

I understand that Kod is being actively developed and is prone to drastic changes in any area. I would like to modify some small things (like font face and size or certain colors) while still being able to benefit from any changes or updates to the default Kod stylesheet. I thought that I would be able to @import the default stylesheet into my own to achieve this. This is what ~/.kod/custom.css would look like, @import url("file:///Applications/Kod.app/Contents/Resources/style/default.css"); /* Change the default font face and color. */ body { font-family: Menlo, monospace; color: #efefef; } This stylesheet was set with the following defaults command, per the comments at the top of Kod's default CSS file: defaults write se.hunch.kod style/url ~/.kod/custom.css Unfortunately, this didn't work. When I first tried to reload the style, Kod crashed. It opened fine again, but the @import statement wasn't working, and Kod crashed every time I saved the custom.css file. Am I doing something wrong? Did I write my @import statement wrong? Is that not how @import is supposed to work? Did I miss some sort of documentation or Kod Google Groups post that mentions that Kod explicitly disallows this?

Coloring of collapsed threads in mutt

- by Rich

I'm trying to figure out the syntax of colouring collapsed threads in the mutt index. The documentation for mutt patterns doesn't seem to include a description of how this works, and so far I've been completely unable to figure it out by trial and error. What I'd like is for collapsed threads that contain any unread (new) messages to be always coloured green. If collapsed threads with no unread messages contain any flagged messages, then I'd like them to be red. So far, every set of patterns I've tried results in threads that contain both flagged and unread messages being coloured red (I want them green). These work: color index green default "~N" # unread messages color index green default "~N~F" # unread flagged messages color index red default "~F" # flagged messages color index green default "~v~(~N)" # collapsed thread with unread But these don't: color index green default "~v~(~N~F)" # attempt to keep threads with unread green color index red default "~v~(~F)" # colours collapsed threads with flagged and unread red color index red default "~v~(!~N~F)" # ditto color index red default "~v~(^!~N~F)" # ditto color index red default "~v~(~F)~(!~N)" # ditto color index red default "~v~(~F)~v~(!~N)" # ditto I've also tried switching the order of the "~v~(~F)" and "~v~(~N)" commands in the file, but the "flagged" rule always seems to take precedence over the "new" rule. Ideally I'd like to understand how the syntax for colouring collapsed threads works, but at this point I'd happily settle for a set of rules that achieves the colourscheme described above.

Do I need a helper column, or can I do this with a formula?

- by dwwilson66

I am using this formula =IF((LEFT($B26,2)="<p"),0,IF($B26="",0,IF($F26<>"",0,(FIND("""../",$B26))))) To parse data similar to the following. <nobr>    contractor information</nobr><br>       <a href="../City_Electrical_Inspectors.htm"><b> City Electrical Inspectors</b></a><br> <nobr>    <a href="../City_Electrical_Inspectors.htm"><b>inspection</b></a></nobr><br> My problem comes in cases such as the first line, in which the line is not a new paragraph nor a link, and my FIND returns an error of #VALUE! Id like to create an IF test to scan the line for the existence of the pattern in my FIND statement before processing that statement. I figured that looking for an error condition may be the way to go. However, the only way I can envision this is as a self-referential formula, similart to the following pseudocode. IF(ISERROR($L26)=TRUE,$L26=0,L$26=the-result-of-the-formula-above) Can this be done with a formula or do I need to use a new helper column? Thanks.
