What are all these question marks? This is not the format for a geometry in Tk. They usually look something like these:

$widget->geometry('640x480');   # Big as a VGA Screen
$widget->geometry('+100+200');  # Slightly down to the right
$widget->geometry('600x800+50+50'); # Big, out of corner

And other variations. "perldoc Tk::Wm" for more details and options.
