the file you sent to me is named srInsert.php
you have the forms action set to post to another page, servicereq_Insert.php:
<form action="servicereq_Insert.php" method="post" name="WADAInsertForm" id="WADAInsertForm">
All form processing must occur on the forms action page
none of the behaviors on this page will ever trigger on form submit since the form submits to another page.
either change the forms action to be blank so it will post to itself:
<form action="" method="post" name="WADAInsertForm" id="WADAInsertForm">
or add the behaviors that will precess the form to the servicereq_Insert.php page.
