Move main timeline (stage) from inside movieclip

Hi everyone,

I have an animation (movieclipX) on frame 2 of main timeline. After movieclipX is finished playing, at the end of movieclipX I’d like the main timeline to move to the next frame, frame 3.

How can I do this??

Sorry if this is an easy question, I’m in the process of learning…

thanks a lot! Will appreciate your help
