Try removing the 'use strict;' statement. See w

Hi, Bret
You must tell perl what kinds of var the $i is, when 'use strict'. $i can be
a lexical var or a global var.
my $i = 1; # $i is a lexical var.
our $i = 1; # $i is a global var, perl 5.6+ only.
use vars qw($i); # also as global var, but can work under old perl
