Accessing CGI objects from within a 'require'-ed file?

[Anonymous Monk]

I'm having issues accessing a CGI object in the main namespace from within a 'require'-ed file...For instance, this is my main script:

#!/usr/bin/perl -w

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

require "functions.pl";

# define a hash to contain any "global" objects or variables
our %GLOBAL = (
  'query' => '',
  'test' => 'foobar!'
);

$GLOBAL{'query'} = new CGI;

print CGI::header();
outputTest();
outputPOST();

and this is the library file it requires (functions.pl):

sub outputTest
{
  print $main::GLOBAL{'test'};
}

sub outputPOST
{
  print $main::GLOBAL{'query'}->Vars;
}

1;

running this as-is throws up an Internal Server Error, which is strange considering i'm using fatalsToBrowser. i'm sure the problem is with the CGI query object, because if I remove the outputPost subroutine, it runs fine.

am I just missing something vitally obvious?
