I will take a look at the code to see if anything looks out of place... as far as what I meant about the UE includes, I was referring to the files such as:
<?php require_once("WA_Universal_Email/mail_PHP.php"); ?>
<?php require_once("WA_Universal_Email/MailFormatting_PHP.php"); ?>
I just wanted to make sure those, too, were being placed after the validation and the other stuff... so that the email would be the very last thing that occurs. If the email is the last thing, in theory, it should not have any bearing on the code (including the validation) before it.
