Communicate between Author Time created Movie Clips

[sanDagFlash]

Hello All,

I am new to AS 3 and need to figure out how get some Movie Clips to communicate with with each other or with the Main timeline (Scene 1) .

I have created two movie clips during author time not dynamically
- a movie clip instance named menu_mc and a movie clip named screen_mc.

Inside menu_mc are buttons that I have 'wired' to communicate with a movie clip on the main stage/main timeline .

How can I successfully reference the 'main' timeline and/or the 'screen_mc' clip.

So far the only thing that works is:

this.parent["screen_mc"].gotoAndStop("flower") ; // <-- (Script is written in a keyframe inside menu_mc)

Any help is much appreciated as this was so easy to achieve in AS 2.
