First, ditto on the comments above. You make $f1 a global, but you create the scrolled listbox in another sub using my $f1. The $f1 won't be seen in genchart that way.

You also don't need "use Tk::BrowseEntry" since you are using scrolled listboxes.

Your code is pretty messed up to try and fix, but I will show you how to get the selections out of a set of scrolled listboxes. Notice in the following example, the indice count starts at 0, and to get the text of the indice you need to run $lb->get on it.

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

my $mw = MainWindow->new;
$mw->geometry(q/+100+100/);
$mw->title("Test Script");

#need exportselection=>0 for using multiple selection boxes

my $lb0 = $mw->Listbox(-bg => 'white',
                       -selectmode => 'extended',
                       -exportselection=> 0 )->pack;

$lb0->insert( 'end', qw/foo bar baz/ );


my $lb1 = $mw->Listbox(-bg => 'lightseagreen',
                       -selectmode => 'extended',
                       -exportselection=> 0 )->pack;

$lb1->insert( 'end', 1..20 );

print "$lb0 : $lb1\n";

$mw->Button( -text => "Selections", -command =>
     sub{ print
           "1: ", join(" ", $lb0->curselection), "\n",
           "2: ", join(" ", $lb1->curselection), "\n",
            "\n";
           
           my @selections0 = $lb0->curselection;
           my @selections1 = $lb1->curselection;
           
           foreach my $select (@selections0){ print $lb0->get($select)
+,"\n"}; 
           foreach my $select (@selections1){ print $lb1->get($select)
+,"\n"}; 

        }           
           )->pack( -side => 'left' );

$mw->Button( -text => "Done", -command => \&exit )->pack;

MainLoop;
