Unloading a movienum

Hi,

I have the following code which loads an external gallery.

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

On the same page I have a back button that sends the user back to the main site. And I want to unload the gallery with this back button , but I don’t know what the code would be - everyone i’ve tried sends the page back but the gallery remains in place?

Would be really grateful if anyone could offer any advice?

Thanks

on (release) {
 unloadMovieNum(1);
}

That’s great - thank you.
