Scene Loop again

[monkeygraphik]

Can anyone tell me what code I need to put in the last frame of a loaded external swf that will unload it and then drop me back into scene 1, frame 1?

The external swf is being loaded from frame 1 of scene 2 on the main stage. This is to get around a problem I am having loading above a main stage that has a mask on it. The swf loads up fine. However, when the timeline reaches the last frame I have some code on it that I want to unload itself and gotoandplay scene 1, frame 1. The code I have been trying is;
code//

stop();
unloadMovie(1);
function(){
_root.gotoAndPlay("scene1",1);
}

//code

But this just seems to drop me back into scene 2. Where am I going wrong? Is there another way to do this?

I have uploaded the experiment files I am using so that you can see what I am trying to do.

Thanks for any help.

Tom.
