What's wrong with this "gotoandPlay" script

I'm using Flash 8. I've got a video playing on my main timeline with a series of buttons to the right. Each button is a movie clip in and of itself. The button on that timeline is scripted like this:

on (release) {
_root.gotoAndPlay("integration_intro", 1);
}

I'm wanting to jump to a new scene on the main timeline that will have a different video. It seems simple, but I can't get the buttons to work. I've posted the fla at http://www.hihatwebdesign.com/movie.zip
