Scrolling and xml and video.maru

hi everyone i have this problem and i can’t figure it out. I’m using video.maru and i need to make a scroll bar that would control the linkBTNholder (that’s an empty movieclip and its instance name) the holder puts all the buttons that are in a xml file. i can’t mask the thing because of the dynamic text issue. i have tried to make my own scroll bar but i think because my linkBTNholder is empty that it wont scroll. Would i have to add specific numerical values to the script? and if so could you help me with that. sorry i’m pretty bad when it comes to scripting.
