Aligning objects on browser.

Hi, i got a site designed to fit full screen. Well, now, i want to put a menu on the left side of the screen. I've used this script to make it work:

function fit () {

var SW:Number = Stage.width;
var SH:Number = Stage.height;
tellTarget (topleft_item) {
_x = 0;
_y = 0;
}
tellTarget (topright_item) {
_x = SW - _width - 0;
_y = 0;
}
tellTarget (bottomleft_item) {
_x = 0;
_y = SH - _height - 0;
}
tellTarget (bottomright_item) {
_x = SW - _width - 0;
_y = SH - _height - 0;
}
tellTarget (centered_item) {
_x = SW - SW /2;
_y = SH - SH /2;
}
//make sure that the swf you're loading has the same dimensions as framer
//or change framer to th same dimensions as your loading movie.
tellTarget (framer) {
_x = Math.round(SW / 2 - _width / 2);
_y = Math.round(SH / 2 - _height / 2);
}
}
onSelfEvent (load) {

Stage.scaleMode = "Scale";
Stage.align = "TL";
var rsz:Object = new Object();
rsz.onResize = function ():void { fit ()};
Stage.addListener(rsz);
fit();
}

But now, the proper content of the site is loaded from another movie, but this movie loads on the left too! I need to load this movie on the center of the screen browser. Am I clear? I'm not good with english. Many thanks.

I uploaded a swi file with the example.
