Control timeline of external swf

1

I have a loadMovie function in my timeline that is loading a external swf file. I want a button to control the tim line of the swf file that is loading externally.

I know this is wrong, but kind show what i want to do:


loadMovie("g2.swf", empty_mc)
//button
this.next_btn.onRelease = function() {
	g2.swf.gotoAndPlay("two")
};
