Linking ext swf

Hey, Im trying to link an ext swf into my MC but Ive trying a lot and cant working out. Its supposed to be easy stuff, but I have hammered my mind hours and figure whats wrong. Its a full screen swf.
Im using a blank MC.
Im uding this code (it has a reposition code bfore, the actual one is in red.

Stage.scaleMode = “noscale”;
Stage.align = “tl”;
Stage.addListener({onResize:reposition});
function reposition() {
var mc = _root.nav_mc;
var newX = Math.floor(50);
var newY = Math.floor((Stage.height - mc._height) / 2);
mc._x = newX;
mc._y = newY;
var mc1 = _root.content_mc;
var new1X = Math.floor((Stage.width-mc1._width)/2);
var new1Y = Math.floor((Stage.height-mc1._height)/2);
mc1._x = new1X;
mc1._y = new1Y;
};
reposition();
[COLOR=Red]_root.nombre = “home”;
_root.content_mc.loadMovie(_root.nombre+".swf");[/COLOR]
stop();

It is supposed to work but I cant make it…
Ill post the fla anyway, can anybody help?
