Flash8 AS: Tsunami menu help

Im using the menu found here http://jrgraphix.net/research/flash_dock.php

Only thing is all the icons are compiled into 1 mc and you cant seem to get to each invidual mc. Have listed the objects and they all pop up with IDs “_level0.menu_mc.5._mc”

Whenever I try to reference one like _root.menu_mc.5._alpha = 0; it says it doesnt exist.

Any help would be great :-/
