instead of doing a copy/paste with the contents of the page, please use the Manage Attachments link to actually upload the files so I can view them in Dreamweaver.
It could be an issue with the Trigger. Open the Server Behavior for the email and try changing the trigger to use the button press trigger or "Any form post" instead of "current page submit".
Please attach a copy of the .php page and also add a copy of: webassist/email/waue_contact_1.php
The issue could be in that file. This file looks correct.
