Noob question

This is a very stupid question… :nerd: But I just can’t figure it out.

I have made a square that moves around a little bit (converted it to a mc, of course). On frame 10 of my movie the sqaure is finished moving, so I have made a 2nd layer with actions on it and added a keyframe in the actions layer on frame 10 that says:

stop();

This works fine. The movie stops @ frame 10 and doesn’t repeat itself.

What I want to make is that when you roll over my movie clip in frame 10, it starts playing frame 20. I have already right clicked on my movie clip, and added these actions:

on (release) {
gotoAndPlay(10);
}

I know I am doing something wrong cuz it doesn’t work. It’s probably some simple thing, but I’m just missing something. Can someone help?
