Simple .swf x,y, positioning problem

programming flash
1

With the highlighted lines I’m trying to change the position on the page that the .swf loads to. This is the button code that calls up the external .swf.
Any help?

}
on(release){
loadMovieNum (“scroller1.swf”,1);
_root.onEnterFrame = function(){
if (_level1 != undefined){
[COLOR=“Red”]_level1._x = 300;
_level1._y = 200;[/COLOR]
delete _root.onEnterFrame;
}
}
}
