After form is submitted - blank process.php page instead of redirect

[earcandy]

I know I'm close to having this working. Once the user clicks SUBMIT they end up at a blank process.php page rather then the redirect url specified in FormTools.

Here is my process.php

<?php
 
/**
 * File: process.php
 *
 * This file processes any form submissions for forms already added and configured within Form Tools. To
 * use it, just point your form to this file, like so:
 *
 *   <form method="post" action="/path/to/process.php">
 *
 * Once the form has been added through the Form Tools UI, this script parses the form contents
 * and adds it to the database then redirects the user to whatever page is required. In addition,
 * this script is used to initially set up the form within the database, to map input fields to
 * database columns and types.
