Just copy and paste the form and set the form action to submit to the original page... You don't need to move any php code if the form submits to the page with the php code. 
Just need a bit more clarification - sorry I'm a real beginner - you were saying to set the form action to submit to the original page – The following is the current form action:
<form action="<?php echo ($_SERVER["PHP_SELF"].(isset($_SERVER["QUERY_STRING"])?"?".htmlentities($_SERVER["QUERY_STRING"]):""));?>" method="post" name="WAATKLogInForm" id="WAATKLogInForm">
...how do I change the code so that the action is submitting to the rego page? Is this right - I mean the rego page is the page with the php code right? I'm confused.
Also are you saying that I don't need all this extra code below? I was following the tutorials in the Introduction to SecurityAssist solution recipe to encrypt the passwords - won't I need all this on the other page?
