Welcome to the Monastery. Please don't ignore posting advice. Read and understand:

• How do I compose an effective node title?
• How do I post a question effectively?
• Markup in the Monastery

There is no such thing as PERL (see Re^3: Writing to Spreadsheets in PERL...). You've posted a script with no description of any problems you're having. Your script should have:

use strict;
use warnings;
[download]

You should read Ovid's CGI Course - Resurrected and Updated! as well as some of Web Programming from the tutorials section of this site.

Update: You've changed the post title.

Update 2: Looks like a problem with your here-document: Quote and Quote-like Operators. END_OF_PRINT should be HTML. Consider using something like HTML::Template to separate your HTML/JavaScript from your Perl code.

Update 3: You have:

# Print HTTP Header
print &PrintHeader;
[download]

This isn't part of CGI and doesnt exist in the code you've posted. See 'Creating a standard HTTP header' in the CGI documentation.
