the pages have the forms action hard coded:
<form action="../directory2/directory_Update.php?ID=<?php echo(rawurlencode($row_WADAdirectory['ID'])); ?>" method="post" name="WADAUpdateForm" id="WADAUpdateForm">
so if you rename the page, you will also need to modify the forms action so that it will go to that page. Right now, you have the userupdateTEST2.php posting the information to the directory_Update.php page.
