I have no access to Perl modules, i use shared hosting.

I have used various web hosting providers, but I've always had the CGI module. I'm pretty sure it comes as standard with all Perl distributions, so it would be very unlikely that you don't already have it. If you genuinely don't have it, you should give your hosting provider a good kicking.

By the way - the monk who advised using CGI::Carp made a small typo, which would give you an error. The line should be:

use CGI::Carp qw(fatalsToBrowser);

and this (along with use strict) should go straight after the #! line at the start of your file:

#!/usr/bin/perl -w

use strict;
use CGI;
use CGI::Carp qw(fatalsToBrowser);

Hope this helps.
