That's another error that means you haven't declared your variables.
When you use strict 'vars', you have three options for each variable.
Declare it with my:
my $lexical_variable;
$lexical_variable = 7;
print $lexical_variable;
Declare it with use vars:
use vars qw/ $global_variable /;
$global_variable = 7;
print $global_variable;
Specify the package name every time you use it:
$main::global_variable = 7;
print $main::global_variable;
Most people prefer the first two options.
