[thelist] NN Form validation

try the onSubmit() event handler:

<form action="" method="" onSubmit="return isValidData()">

then in your script:

<script>
function isValidData()
{
  if (document.formname.formelement1.value == "")
  {
    alert("You did not enter a value for 1!");
    return false;
  }

  if (document.formname.formelement2.value == "")
  {
    alert("You did not enter a value for 2!");
    return false;
  }

  return true;
}
</script>
