I feel really stupid but it was a file location issue. It's working now. The only problem I have remaining is on my thank you page I am referencing the FIRSTNAME and LASTNAME from the form so it reads "Thank you, we received your submission for JOHN SMITH". On WAMP it just appears blank, but on the external web server it appears JOHN SMITH (or whatever was input).
When you click submit on the form it triggers sendrequest.php. The thank you page is part of the sendrequest.php file. Here is the code that references the FIRSTNAME and LASTNAME fields in the body of the HTML...
<?= $firstname ?>
<?= $lastname ?>
Could this be a PHP version issue? My web server supports PHP 4.0.3 and 5.0...
