My first post ever on kirupa (finally)...please be nice (AS3 question)

Hi everyone, I’ve browsed this site off and on for quite a while and finally making what I believe is my first post (unless i’m forgetting).

I’ve searched and searched and googled before finally deciding to pose this question, but I just can’t figure this out.

What is the best way to get 3 buttons that are nested inside a movieclip to control the main timeline?

I know this MUST have been covered before and i’m just not doing a good job with my search, but there it is. Asked once again for you all lol
