Unload movie help?

hello,

I need help.

Am building a site and i have used this code to load different pages:-

on (release) {
loadMovieNum(“movie name.swf”, 1);
}

when i test the site and click on a link to a new page, it load the new page but over the pervious one, which you can see both of the movies. Is there a way to unload the pervious page so it don’t show up underneath?:a:
