How can I make a button inside a MovieClip control its own timeline?

Hello,

I created a Movie Clip with a button inside it. The Movie Clip contains simple animation within its timeline. I dragged the Movie Clip to the main stage and tested the movie/ My goal is to have the button start the animation inside the Movie Clips timeline but it is not working.

The Movie Clip instance is named ‘film_mc’ and the button inside it is named ‘first_btn.’ The frame is labeled ‘one’. I tried these two Action Scripts that I put on the main timeline. Where am I going wrong? Thanks for any input.

film_mc.first_btn.onRelease=function(){
film_mc.gotoAndPlay(“one”);
}

film_mc.first_btn.onRelease=function(){
this.film_mc.gotoAndPlay(“one”);
}
