How to make a Movie Clip symbol plays when click on it?

Hi,

I am using Flash MX 2004.

Layer 1 - A simple movie clip symbol moves from Frame 1 to Frame 30
Layer 2 - I apply an actionscript stop(); on Frame 1 so that the movie stop at the beginning

I wish the movie clip symbol play when I click on it. How can I do that?

P.S. I tried to use the following AS on the movie clip but it fail.

on (release) {
play();
}

Thanks and best regards

Alex
