Navigating thru a full flash site question!

okay. really need some help.

lets say i have my main fla. & on the scene, I have a ‘loadmovie’ action that loads a external swf, say “anim1” to a movie clip on the stage called ‘contents’ using

stop();
_root.contents.loadMovie(“anim1.swf”);

in that MC there is a button…Now i want that button, say “button1” to load another external swf, say “anim2”

anyone could tell me how to do that?

I tried

on (release) {
_root.contents.loadMovie(“anim2.swf”);
}

but it didnt work? any ideas?
