You could also use -textvariable with your Entry widget.

#!/usr/bin/perl

use strict;
use warnings;

use Tk;

my $name;

my $main = MainWindow->new();
$main->Label(-text=>"Company Name:")->pack();
my $entry = $main->Entry(-textvariable => \$name)->pack;
$entry->focus();
$main->Button(-text=>"Continue", -command=> sub {$main->destroy;})->pa
+ck();
$main->Button(-text=>"Cancel", -command => sub {exit})->pack();
$main->bind('<Return>' => sub {$main->destroy});
MainLoop;
die "$name";

Update
Oops... I forgot to put in the reason for the first code not working -- the problem is that the "$name = $entry->get();" line is being executed before there is a value in the Entry widget (You can't use the interface before the MainLoop;)

Here is a "fix" for the first example:

#!/usr/bin/perl

use strict;
use warnings;

use Tk;

my $name;

my $main = MainWindow->new();
$main->Label(-text=>"Company Name:")->pack();
my $entry = $main->Entry()->pack;
$entry->focus();
$main->Button(-text=>"Continue", -command=> sub {$name = $entry->get()
+;$main->destroy;})->pack();
$main->Button(-text=>"Cancel", -command => sub {exit})->pack();
$main->bind('<Return>' => sub {$main->destroy});
MainLoop;
die "$name";

Yeah, what arden said. *Smiles*
