OK on the Index.php file you you change anything? If you changed the input names on that file you must change on the file you just posted.

Example If you have a line in index file that says

*Game Name:
<input name="Input1" type="text" value="" size="15">

then on the apply file that actually sends you the email, you must have it say

$App = "Game Name: $Input1\n

The $Input1 part is case sensitive. It tells that script to get the gamename that they entered above. If you changed any of this in Index file, you must do so in apply file.
