It looks like you removed the Server Validation, but still have the fields populated from the Validated Fields bindings. That is what is causing the issue.
The solution is to either remove all of the form field value references that are referring to the validated fields, or add back the include file:
<?php require_once("webassist/form_validations/wavt_validatedform_php.php"); ?>
I've done the latter on your page and it displays now.
