Your code as posted doesn't compile. You've got a couple of typos in it...

Try this:

#! /usr/bin/perl 
use warnings;
use strict;
use Tk;

my $mw = MainWindow->new;
$mw->title("Checkbutton Grid");

my $x_size = 5;
my $y_size = 5;
my %b_name;

for (my $x=0; $x<$x_size; ++$x) {
  for (my $y=0; $y<$y_size; ++$y) {
    $mw -> Checkbutton (
           -activebackground => "white",
           -command => sub { print "$x,$y\n";
                       print "hi"; }
                       ) -> grid (
               -row => $x,
               -column => $y
                );
  }
}

MainLoop;

Note that when you want to call a subroutine in a -command line, you need to use the sub { ... } language. Note also that the values for $x and $y will be $x_size and $y_size respectively, because by the time you click on a check button, they've been incremented to those values - where they remain.

What you need to do is to associate a value (x, y) with each of the check buttons, and then use the value in your print statement.
