Submit to Web; PHP

[tealmad]

First of all, I would like to say that I am very impressed with SUF6.0. The application is extremely flexible for all of my needs. However, I have a question that I need answered and it has been eating at my brain:

I am collecting information from my installers: Name & Email Address. I want to be able to submit the collected information to a PHP script that writes the information to a tect file on my site. When I wrote the script, it didn't work. The application ran, however, the text file was not updated with the information submitted. I did follow the information provided in the help file in SUF. My PHP script was as follows:

<?php
if (!$save = fopen("test.txt","a")) {
exit;
}
fwrite($save,"$UserName\r\n");
fwrite($save,"$UserEmail\r\n");
fclose($save);
?>

In SUF, my edit fields &amp; text stored in variables were as follows:
Name: %UserName%
Email Address: %UserEmail%

My Parameters name for Submit to Web were as follows:

USER EMAIL:
Name: UserEmail
Value: %UserEmail%

USER NAME:
Name: UserName
Value: %UserName%

Any thoughts on what I am doing wrong?

Thanks,

Gregg
