I have a perl Tk gui which is used to run a script i have got all the stdout and stderr from the script to print in the text widget. It also has a help button which inserts a txt file into the text widget. I im trying to get stderr messages from the gui itself to show in the text widget, for example if any of the 'or die' warnings are trigered due to files not being available the 'error' pop up box appears,but if there is an error opening the sub runscripts report.pl, the warning appears in the cmd prompt screen, i want it to appear in the gui popup warning box.

use warnings;
use strict;
use Tk;
use POSIX 'strftime';
use Tk::ErrorDialog;
my $DATE = strftime("  report.pl for %d %b %Y " , localtime());
my $title = strftime(" Processing daily Failures for %d %B %Y" , local
+time());
my $mw = MainWindow->new;
my $filenameA = "c:\\Temp\\perl.txt";


$mw->geometry("720x500");
$mw->title("   report  ");


my $main_frame = $mw->Frame()->pack(-side => 'top', -fill => 'x');
my $left_frame = $main_frame->Frame(-background => "snow2")->pack(-sid
+e => 'left', -fill => 'y');
my $right_frame = $main_frame->Scrolled("Text", -scrollbars => 'se',-b
+ackground => "black",-foreground => "green",-height => '44')->pack(-e
+xpand => 1, -fill => 'both');


my $failures_button = $left_frame->Button(-text => "$DATE ",
                                -command => [\&runscript])->pack;
my $guide = $left_frame->Button(-text => "           Clear Screen     
+         ",
                                -command => [\&clear_screen])->pack;
my $Close_button = $left_frame->Button(-text => '                Exit 
+                   ',
-command => [$mw => 'destroy'])->pack;    

my $Help_button = $left_frame->Button(-text => "            Help Guide
+                ",
                                -command => \&help_file)->pack(-side =
+> "bottom");    

my $About = $left_frame->Button(-text => '                About       
+             ',
-command => \&About_file)->pack(-side => "bottom");                   
+
