Dear monks

I am trying to modify my script below and add a Tk Checkbox to my pop-up menu. Unfortunately I am not able to do it. Somebody can help?

#use strict;
use warnings;
use Tk;
my $mw = tkinit();
my $CkAutomaticBackUp;
my $b1 = $mw->Button(
    -text => "Hello",
);
$b1->grid(-row => 0, -column => 1,);
Popup($mw, $b1);
$mw->MainLoop;

    
sub Popup{
  my ($mw, $obj) = @_;
  my $menu = $mw->Menu(-tearoff=>0, -menuitems=>[
    [command=>"Something", -command=>[sub {print "Hello"}, $obj,]],
    #[checkbutton=>(-label =>"Prompt for automatic backup",-variable=>
+\$CkAutomaticBackUp,-onvalue=>'1', -offvalue=>'0', -compound => 'left
+'), -command=>[sub {print "$CkAutomaticBackUp"}, $obj,]],
    ]);
    $obj->menu($menu);
    $obj->bind('<ButtonPress>', ['PostPopupMenu', Ev('X'), Ev('Y'), ])
+;
    return $obj;
}
