Dats my code, awfully long, huh?
Well anyways I got most of it from here, however I get an error on line 67 saying "TypeError: 'undefined' is not a function.".
I'm using Steroids (phonegap-like) and testing dis on an iPhone simulator. I'm sure it uses some cordova for the database work.
Thank you for your help :-)
