asp radio button array validation
 
HI

I want to validate a form which has approx 36 fields in which I accpt the reponses from radio button (yes/NO/NA). I need to know the Javascript which would validate all the 36 field radio buttons in an array and return the pointer where the radio button was left and not selected.
-----------------
<td width="68" align="center"><input type="radio" value="1" name="OP_1" onClick=0></td>
        <td width="68" align="center"><input type="radio" value="2" name="OP_1" onClick=0></td>
        <td width="69" align="center"><input type="radio" value="0" name="OP_1" onClick=0></td>
        <td type "hidden" width="5" align="center">
-------------------
<td width="68" align="center"><input type="radio" value="1" name="OP_2"></td>
        <td width="68" align="center"><input type="radio" value="2" name="OP_2"></td>
        <td width="69" align="center"><input type="radio" value="0" name="OP_2"></td>
--------------
<td width="68" align="center"><input type="radio" value="1" name="OP_3"></td>
        <td width="68" align="center"><input type="radio" value="2" name="OP_3"></td>
        <td width="69" align="center"><input type="radio" value="0" name="OP_3"></td>
---------

The above examples state 3 fields, there are 33 more like this.
Please help

here is a JavaScript that would look for all the radio button and see what there status is if emptyl/unchecked it would simply say please check all radio buttons.


Code in JavaScript

for (i=0, n=theForm.radios.length; i<n; i++) {
if (theForm.radios[i].checked) {
     var checkvalue = theForm.radios[i].value;
     break;
}
}
why += checkRadio(checkvalue);

function checkRadio(checkvalue) {
var error = "";
if (!(checkvalue)) {
     error = "Please check a radio button.\n";
    }
return error;
}

My 2cents worth - Most people look at radio button and assume limited selections should be made. IMO checkboxes should be used if you would like many selections. Am I a bit old school, or is this still the case?
