Eew. Your link is wrong, it's http://fmem.crghosting.com/fp_mailer.txt.

Your first assignment is to add these lines near the top of your script:

use strict;
use warnings;
use CGI::Carp qw/fatalsToBrowser/;
[download]

This will show you a lot of problems with your code. Once you've eliminated all warnings and errors pointed out by warnings and strict, I'd be happy to answer questions.
