I have a simple HTML form that originally was a series of Questions (A1 to A5 and B1 to B3) with yes/no radio buttons like this:

<tr>
      <td width="88%" valign="top" class="field_name_left">A1</td>
      <td width="12%" valign="top" class="field_data">         
                    <input type="radio" name="CriteriaA1" value="Yes">Yes<input     type="radio" name="CriteriaA1" value="No">No</td>
</tr>

The user could only answer either the A series of questions OR either the B series of questions, but not both. Also they must complete all questions in either the A or B series.

I now have an additional series of questions - C1 to C6 - and need to extend my validation scripts to ensure the user enters either A, B or C and answers all questions within each series.

My original script for just the A and B looks like this:

    $(function() {

        $("#editRecord").submit(function(){

        // is anything checked?
        if(!checkEmpty()){
            $("#error").html("Please check something before submitting");
            //alert("nothing Checked");
            return false;
        }
        // Only A _OR_ B
        if(isAorB()){
            $("#error").html("Please complete A or B, not both");
            //alert("please complete A or B, not both");
            return false;
        };
        // all A's or all B's
        if(allAorBChecked()){
            $("#error").html("It appears you have not completed all questions");
            //alert("missing data");
            return false;
        };
        if(haveNo()){
            // we're going on, but sending "type = C"
        }
        //alert("all OK");
            return true;
        });
    });


function checkEmpty(){
    var OK = false;
    $(":radio").each(function(){
        if (this.checked){
            OK = true;
        }
    });
    return OK;
}
 function isAorB(){
    var OK = false;
    var Achecked = false;
    var Bchecked = false;
    $(":radio").each(function(){
        var theChar=this.name.charAt(8);
        // if we have an A checked remember it
         if(theChar == "A" && this.checked && !Achecked){
            Achecked = true;    
        }
        if(Achecked && theChar == "B" && !Bchecked){
            if(this.checked){
                Bchecked = true;
            }
        }
        if (Achecked && Bchecked){
            OK = true;
        }
    });
    return OK;
} 
function allAorBChecked(){
    var notOK = false;
    var Achecked = false;
    $(":radio").each(function(){
        // skip through to see if we're doing A's or B's
    var theChar=this.name.charAt(8);
        // check the A's
     if(theChar == "A" && this.checked && !Achecked){
            Achecked = true;    
        }

    });
    if(Achecked){
        // set the input to A
        $("#type").val("A");
        // check _all_ a's are checked
        var thisName;
        var thisChecked = false;

        $(":radio").each(function(){
            var theChar=this.name.charAt(8);
            var checked = this.checked;
            if (theChar == "A"){
            if (this.name == thisName && !thisChecked){
                // Yes wasn't checked - is No?
                if(!checked){
                    notOK = true;
                }
            }
            thisChecked = checked;
            thisName = this.name;
        }
    });
    }else{
        // set the input to B
        $("#type").val("B");            
        // check _all_ b's are checked
            var thisName;
            var thisChecked = false;
            $(":radio").each(function(){
                var theChar=this.name.charAt(8);
                var checked = this.checked;
                if (theChar == "B"){
                if (this.name == thisName && !thisChecked){
                    // A wasn't checked - is B?
                    if(!checked){
                        notOK = true;
                    }
                }
                thisChecked = checked;
                thisName = this.name;
            }
        });
    }
    return notOK;
}    
function haveNo(){
    var thisName;
    var notOK = false;
        $(":radio").each(function(){
            var checked = this.checked;
            if (this.name == thisName){
                //Is this checked 
                if(checked){
                    notOK = true;
                    $("#type").val("C");            
                }

        }
        thisName = this.name;
    });

    return notOK;
}

This worked well but I'm completely stuck at extending it to include the C series. I now have to check that the user hasn't answered any A and B, A and C and B and C questions. Everything I've tried fails to validate. Here's where I'm at right now with my new script:

    $(function() {

        $("#editRecord").submit(function(){

        // is anything checked?
        if(!checkEmpty()){
            $("#error").html("Please check something before submitting");
            //alert("nothing Checked");
            return false;
        }
        // Only A or B or C
        if(isAorBorC()){
            $("#error").html("Please complete A or B or C, not both");
            //alert("please complete A or B, not both");
            return false;
        };
        // all A's or all B's or all C's
        if(allAorBorCChecked()){
            $("#error").html("It appears you have not completed all questions");
            //alert("missing data");
            return false;
        };
        if(haveNo()){
            // we're going on, but sending "type = C"
        }
        //alert("all OK");
            return true;
        });
    });

Anyone see what I'm doing wrong?
