May need to add to your <form> tag. Once the Javascript does the form
validation, it needs to know where to send the form data. You have the method
set to "post" but were missing the action setting. If you are sending the form
back to itself you can usually specify that in PHP using...
<form action="<?php $PHP_SELF; ?>" method="post">
You might need to pull the "onClick" event from your submit button and include
that in the form tag as well.
