LoadMovie in AS3.. Please help :)

I need some help with my gallery.
I have 2 files.

web.fla and gallery.swf
i want to load the gallery file into web.fla, but i have a problem.
When i press the buttons it work fine, except when i want to go to the gallery, and then after that to another page.
Once i have entered the page with the gallery, and want to move on to a different page the gallery continues to be there on every single page.
I don’t have a lot of experience i asctionscript 3, so experts… please help me :proud:

Have a look at the code:

hjem.addEventListener(
MouseEvent.MOUSE_UP,
function(evt:MouseEvent):void {
gotoAndPlay(“billede1”);
}
);
biografi.addEventListener(
MouseEvent.MOUSE_UP,
function(evt:MouseEvent):void {
gotoAndPlay(“billede2”);

}
);
art.addEventListener(
MouseEvent.MOUSE_UP,
function(evt:MouseEvent):void {
gotoAndPlay(“billede3”);

var ld:Loader = new Loader()
ld.load(new URLRequest(“galleri.swf”))
addChild(ld)
}
);
kontakt.addEventListener(
MouseEvent.MOUSE_UP,
function(evt:MouseEvent):void {
gotoAndPlay(“billede4”);
}
);
