Form validation - multiple fields with the same name not validating properly

I have a form that generates dynamically depending on what is chosen from several dropdowns. This form sometimes generates only 1 data field (txtQFound) and sometimes up to 10 datafields all having the same name (txtQFound).

My JS form validation is not validating this field, perhaps because most of the time there are multiple? How do I do this? I have this validating 6 other fields and the rest of the fields are validating properly.

Current JS validation code (only the field in question):

function validate() {
    errorFields='';
    errorMessage='';
    vQFound=frmQASort.txtQFound.value;

if (vQFound=='') {
         errorFields+=' Quantity Found\n';
         event.returnValue=false;     }

if (errorFields!='') {
         errorMessage+=' The following fields are required:\n\n';
         errorMessage+=errorFields;
         alert(errorMessage);     }}

Of course you were right.. I tried it with just one and it didn't validate, but then used your update fix and it does work no matter the number of input fields..

I appreciate you being so thorough, and posting the fix.

thanks again!
