This is what the SYNOPSIS shows

 $whatever = $parent->Scrolled(Whatever ?,-scrollbars=>where? ?,...?);

This is what you have

$vall->Scrolled('Frame', -scrollbars => "ose",)->pack;
[download]

You don't have $whatever, you create a frame, pack it, and ignore it, and you keep using the frames parent $vall

If you want widgets in the scrolled frame, they have to be children of the scrolled frame
