Remove part of the email body

I am trying to understand how to remove some variables from the email that will be reported.

I want the information of the name,email and comments, but not the security answer or hidden fields. It is present on a received email.

It looks like the email body (float.php) can be changed around a bit to show what you want. I hope that is the case. I would like to remove those dynamic values from the pval array.

The post command is this:
<?php
foreach( $_POST as $pkey => $pval ){
if (!RemoveValue($pkey,$remove,$removeBegins,$removeEnds,$removeIncludes)) {
?>

So do I remove one of these values here or remove it from the contact.php page.

thx

Mike
