Help with scaling a MC in a fluid layout

1

Hello,

I am using the following code on individual movie clips to keep the object centered in a fluid layout:

onClipEvent(load){

this._x= (Stage.width)/2;
this._y= (Stage.height)/2;


Stage.addListener(this)
this.onResize=function(){
	this._x= (Stage.width)/2;
	this._y= (Stage.height)/2;
}

}

My question is this: Cn I add/modify to this code to make the MC scale proportionately up as I drag the browser window farther open?

Right now it stays centered but it stays the same size.

I am a cut and paster with code so be gentle.

Any help would be greatly appreciated.

Thank you
