I'm not exactly sure what you are trying to do, but you will
need to output an http header so the web page can be
displayed. I would suggest using CGI.pm as follows

#!/usr/bin/perl -w

use strict;
use CGI;
use CGI::Carp qw(fatalsTo Browser);

my $page = new CGI;
print $page->header()
print $page->start_html();
...
..
.
print $page->end_html();

Hope this helps, if not post a bit more of your code
