Hi,

I'm working on a script and at one point the script calls up a subroutine located in an external file. In that external subroutine, it tries to print a variable that is located in the original script file. I can do this fine but I'm working in Perl Tk where it always asks you to use the "my" function to declare variables. That little function required in Perl/Tk causes my problem and I was wondering if anyone knew a way around it. Heres some code example to make this a little easier to understand: 
require "external_subs.txt";

my $a = 1;
my $b = blue;

  if($a == 1) {
        &numbers
      } else{ die;

That would be the main script file and this would be the external file, "external_subs.txt" : 
sub numbers {
        print "$b";
     }

1;

[download]
If you take out the 'my' fuctions, the whole thing works fine as you can see. But put them in and your stuck in my situation. =\

Also I'm using ActiveState 5.6.1 on Windows XP. Any help would be greatly appreciated! Thanks.
