How I can control the "unloadMovie" command?

1

Hello . I have a problem

Is it posible to control the unloadMovie command?
Like that I can unload a movie after I have playd a movie clip

My Button actionscript is *** follow:

on (release) {
unloadMovieNum(10);
_root.sweet.buttonpressed = true;
_root.sweet.mynewmovie = “gallery3.swf”;
}
on (release) {
tellTarget ("_root.LogoMovie") {
if (Number(_currentframe)>2) {
gotoAndPlay(“25”);
}
}
}

I like to unload the movie after & only if the _currentframe is >2

Thanks
