[Javascript] multiple onSubmit events not working

When you use "return check_upload_required;" it does exactly that -
returns with the value that came back from the function, and therefore
stops processing any code after that point.

Try defining a single function:

function submitHandler(theForm) {
   var result = check_upload_required;
   if (result) {
      openpopup();
      submitonce(theForm);
   }
   return result;
}

and change the handler to

onsubmit="return submitHandler(this);"

HTH,

Nick.
