You've been here for 17 years and made almost 450 posts. Why is it so difficult for you to understand that an error message without the source code is completely meaningless? How are we supposed to know what's at line "nn"? How are we supposed to know what "Perl script" refers to?

Here's the guts of what you probably need: 

#!/usr/bin/env perl

use strict;
use warnings;

use Tk;
use Tk::DynaTabFrame;

my $mw = MainWindow::->new();

my $dtf = $mw->DynaTabFrame()->pack(qw{-fill both -expand 1});

my $dtf_static = $dtf->add(Static => qw{-label Static});
my $dtf_transient = $dtf->add(Transient => qw{-label Transient});

$mw->Button(-text => 'Show', -command => sub {
    $dtf->pageconfigure(Transient => qw{-hidden 0})
})->pack;

$mw->Button(-text => 'Hide', -command => sub {
    $dtf->pageconfigure(Transient => qw{-hidden 1})
})->pack;

MainLoop;

Although barebones, this works as is. This is the type of code that your SSCCE should contain. All of your error or warnings messages should be provided verbatim within <code>...</code> tags. Read, and fully understand, "How do I post a question effectively?" before posting again.
