Movie clip as button


I am relatively new to Flash and I have a problem which I have desperately tried to fix, but cannot. I have a movie clip that I would like to have the properties of a button. To be more specific, it is moving text that when you rollover it stops and when you click it goes to a certain part of the site. The rollover works, but I cannot get an on(release), gotoAndPlay to work.

Thank you very much for your time,
