Problem with Scrolling Text tool.

[Vent]

Hello, I am using the scrollable text tool posted by Trickster in my RPG. I am trying to make my help windows automatically scroll text but nothinghappens and it remains the same.
Here are the areas that I edited.
At the start of main in Scene_Item:

@help_window = Window_Scrollable.new(0, 0, 640,64)
    @help_window.contents_rect = Rect.new(0, 0, 614, 32)
    @help_window.horizontal_scroll = true
    @help_window.speed = 2
    @item_window = Window_Item.new

Instead of making a help window I used the scrollable window.

Also I added the set_text method from Window_Help to the Window_Scrollable script so that the item window would draw text in it.
All that happens when I select items with long descriptions is the text gets compressed and doesnt scroll.

Does anybody know what I am doing wrong? Does the Scrollable text window need to be active? (script is below)

Here's the Window_Scrollable script posted by Trickster.
