[F8] Scroll Bar

I know that FLash 8 has a scroll bar component. And I know how to target that component to an instance name, Can I use that scroll bar to scroll a symbol? I can attach the scrollbar to the symbol, however it doesn't recognize that it needs to scroll anything because although i'm hiing whats not visible with a Mask, it doesn't recognize it as not being visible?

Thank MAKE Sense!? lol

HELP!

Thanks
