OK, I need a scrollbar that can do this

Hello, I’ve prtty much downloaded every fullscreen scrollbar I could find, a lot from here, and google, oringe.com, etc etc etc.

I don’t know how to go about this, but I desperately need a scrollbar that can do this:

-Have a “cutoff” _y value. Something I can specify at anytime (not just onResize) that tells the scrollbar to only scroll to the cutoff Y value. All the scrollbars I’ve found scroll down wayyy too far (they don’t in testing, but when I load my external swf into it, they all do. It must be something with the swf I’m loading, but I can’t really change much)

-Have a scrollTo() function. Something that acts like an anchor tag in HTML. I could put the scrollTo() function on a movie clip (onRelease) and it would tell the scrollbar to scroll to the specified y value.

-easing+mousewheel support - not as important, but would be nice.

Basically, I really need a simple simple scrollbar that can have a cutoff._y value, and a scrollTo(y_value); Easing would be good, even if it’s just for the scrollTo() function (so it doesnt jump down to the point).

Please, any help would be great, even in helping me write my own scrollbar (I have NO idea where to even start)

Thank you very much!

P.S. the scrollbar will be used for this site: http://therealnickhansen.com/sub
(notice how it scrolls down super far?)
