Xml photogalerry with back button

I have done the xml photogallery and I have it as an external swf.On my main page I have 6 buttons representing diffrent photo gallery and in each button I have code

on (release) {
container.loadMovie(“photogallery1.swf”);

}

So basicly when I click on 1 of 6 btn a gallery pop ups.And that’s ok.But now I want to other pics to disapear when one of the galleries load and to have a BACK button wich would unload the movie and return to the previous selection.I tried using

on (release) {
this.unloadMovie(“photogallery1.swf”);

but this makes the movie to unload and after that I have white screen.

Ok somehow I’ve figured out and use this code on back button
on(release){
this.container.unloadMovie()
}

but now I want to to other buttons disappear.Any hints plzz
