Loading Movie Clips without Rollover/release

I am building a flash website that uses buttons that once clicked, a segment of a movie plays (which is actually a sub page that appears). How can i get the portion of my movie clip labeled at point “home” to play initially when the main page is loaded? is there code that i can put on a graphic that will initially load that says something like on (load) play(“Home”)?
I used this page http://www.kirupa.com/developer/flash5/advroll.htm to help me create my pages and buttons, only i used ‘on release’ instead ‘on rollover’.
Anybody have any ideas?
