Hello monks,

Basically I want to do something similar to a wizard, as in have several sequential windows stepping through. I can't seem to be able to get my 'next' button working properly. What I want it to do is call a sub, which would be the code of the next window, or a .pl file which contains the code for the next window and then exit the current one.
To help you understand here is an example of something similar to what I want to do (with the same problem I have, but I did it to make it easier to locate the problem):

use Tk;

my $mw = MainWindow->new;
$mw->title("Window1");
$mw->MainWindow->Frame(-relief=>'groove');
$mw->minsize(600,300);

my $welcome = $mw-> Message(-font => '16', -text =>"Hello World!")->pa
+ck(-side => 'left', -anchor=>'ne');

my $bf = $mw-> Frame(-pady => '5')->pack(-side => 'bottom', -anchor=>'
+se');
my $cancel = $bf -> Button(-relief=> 'raised', -borderwidth => '2', -t
+ext => "Cancel", -command => sub { exit })->pack(-side => 'right',-pa
+dx => '20');
my $next = $bf -> Button(-relief=> 'raised', -borderwidth => '2', -tex
+t => "Next", -command => sub { \&rep2 , exit})->pack(-side => 'right'
+);
my $back = $bf -> Button(-state => 'disabled', -relief=> 'raised', -bo
+rderwidth => '2', -text => "Back")->pack(-side => 'right');

MainLoop;


sub rep2 {

    my $rep2 = MainWindow->new;
    $rep2->tittle("Window2");
    $rep2->minsize(600,300);
    
    my $bf = $rep2-> Frame(-pady => '5')->pack(-side => 'bottom', -anc
+hor=>'se');
    my $msg = $rep2-> Message(-text => "This is the second window.")->
+pack();
    my $finish = $bf -> Button(-relief=> 'raised', -borderwidth => '2'
+, -text => "Finish", -command => sub{exit})->pack(-side => 'right'); 
+   
    
    MainLoop;
    
}

This doesn't seem to work and in the -command of the "next" button if I put: -command => \&rep2 instead it creates new random empty windows and doesn't recognize the tittle or minimum size set for it.Could you please help me?

Thank you for your efforts :)
