loadMovieNum and unloadMovieNum

Ok I have to make a flash site for my motion design class by linking swfs. My intro movie is loaded into level 1. There is a button in my intro movie that when clicked will load my next movie into level 1, thereby knocking out the intro movie. However, the hit area of the button that’s in the intro movie remains. I tried using unloadMovieNum like so:

[FONT=Courier New]on (release){

unloadMovieNum(2);
loadMovieNum("intro.swf", 2);

}

What am I doing wrong?
