Question about scrollbar

Hi I’m newbie on this board, could someone point me to a link tutorial or sample file of a Scrollbar in AS2, I want a portion box to have scrollbar, but this box is not normall because it has a series of movie and graphic item inside the box. here is the picture sample

the red part is the items and has tons of pic item and I want it to have a scroller that can drag up and down as seen on the sample image, thanks
