Cant unload movies on two different levels?

Question

Hi guys,
I am having trouble with unload an loading movies. Basically I am loading a movie into a container, which works a charm:
graphicsbut.onRelease = function() {
_root.createEmptyMovieClip("container",1);
loadMovie("Graphics/Graphics.swf","container");
container._x = -22 ;
container._y = 0 ;
And then I want to load another movie above this one, also working:
Dyson_hit.onRelease = function()
Dyson_mc.gotoAndPlay("out");
loadMovieNum("Graphics/Catwalks.swf", 2);
disableBtns();
But NOW the problem....I want to unload them both when a close button is pressed on the third loaded swf?
Also, ideally I would like to add that second movie clip into a container, so I can position it correctly, but when I try copying the code I use on the first, it doesn't seem to work...is it to do with the "root" bit perhaps?

Answer 1

to load both into a container movieclip:
graphicsbut.onRelease = function() {
_root.createEmptyMovieClip("container",1);
loadMovie("Graphics/Graphics.swf","container");
container._x = -22 ;
container._y = 0 ;
And then I want to load another movie above this one, also working:
Dyson_hit.onRelease = function()
Dyson_mc.gotoAndPlay("out");
_root.createEmptyMovieClip("container2",2);  // use higher depth and different name
loadMovie("Graphics/Catwalks.swf", _root.container2);
disableBtns();
and you can control movieclips loaded into _levels:  you must wait until loading is complete (ie, use preloader code or an mcl).
