I have a callback assigned to a button: 
use Widget_Lib;
my $var;
my $button = $frame->Button(-text => "merge",
                            -command => sub { 
                             $var=&Widget_Lib::show_list;
                             print "$var"; }

The &show_list is another window with a list I need to pick from. The problem is that the print happens before I've even clicked the OK button on the other window... so I'm not getting the value returned. I have checked the value in the other .pm where the list is generated and it is setting my $picked value.

So I guess I'm asking this. Doesn't the program wait until as subroutine returns before continuing on and running the other commands? And if it does... does anyone know why this might be happening?

Thanks for the help
