[perl-win32-gui] How do I update the contents of a textfield?

[perl-win32-gui]

Now that I have a working textfield (Thanks Aldo.), I need to update the contents 
based with the status of a loop that is running.  However, every time I try to make 
the update, I get a popup error window with the follwing message: "Can't locate  
auto/WIN32/GUI/Textfield/text.al in @INC..."  I get the same results when I try to use 
the change method.  What should I be doing?

<Code Snippet>
sub Process_Button_Click {
        $sample->text("You clicked process.");
}

<End of Snippet>

Thanks,
Greg Howard
