Using FFH Scrollbar: simple question

Hey i got this from flashcomponents.net, its a scrollbar.

This is my question: How do I “link” this scrollbar to a dynamic textbox, and is it possible to have it load the text from an external text file - if so - how?

Also, if anyone knows how to edit the scrollbar that would be kool too

Thanks a lot!

IMPORTANT: IM USING FLASH 2004 7.2
