Vertical scrollable image

I am new to using Flash5 and having problems making a vertical scrolling image. Can anyone please tell me how to do this step by step directions. I am very lost! Have found info on this in Flash MX, but these directions don’t apply to Flash5. I have a graphic which is already a symbol, I created a mask for it. Created the up and down buttons, but I can’t figure what actions to apply to the buttons or the symbol I am trying to scroll.
