Anyone wants to explain to me what's going on?

Hello all

Well I found this on the net, but I am considered a beginner in AS It is a cascading menu, I intend to use it for some website, it is heavily scripted so I have no idea

couple of things I want to know,

  1. Where do I set the submenu button, Let’s say I want it to link to an external swf using loadmovie, loading the movie into an instant name say ‘MainBody’

  2. I want to change the button gfx to something like below… or how can I set the function of the cascading to fit the new design that I have, I just need to know how to set the as of a cascading style.

Any Help is much need… and welcome

thank you in advance
