Actionscript for nav buttons

hi guys,

how can i set some actions to the buttons in my navigation so that when clicked, it plays an animation. when it gets to the end of this animation i want the movie to play another animation that leads into the next section of the site, depending on which button was clicked.

so basically if youre in a section of the site (say news), when you select another section to go to (eg. contact), an animation will play that gets rid of all the news stuff on the screen and then comes back in with the contact animation - as to not have a direct cut to the next scene.

i dont want to make eight or so animations that exit from the news section that have a different gotoAndPlay actions at the end of them. im just hoping there is some actionscript that i can put on each button to tell it what to do and where to go.

hope ive explained this ok!

thank you very much and i hope to hear from you.

all the best,
