Swf 100%

I have a flex swf that has the dimensions for the width and height set to 100%.

When you expand the flex application in a browser window the flex swf expands so that you can see more products.

I am loading this flex swf into a flash swf. I want the flex swf to expand with the page. I have tried using this technique in Flash to get the flex swf to expand (see below, i changed the names to work on my flex swf) it expands the container that i am loading the flex swf into but it does not expand the flex swf. Plus i am not trying to expand the scale i just want the flex swf to be able to show more products if there is room:

[COLOR=RoyalBlue]import flash.display.Stage;
import flash.display.StageAlign;
import flash.display.StageScaleMode;
import flash.events.Event;

var swfStage:Stage = videoScreen.stage;
swfStage.scaleMode = StageScaleMode.NO_SCALE;
swfStage.align = StageAlign.TOP_LEFT;

function resizeDisplay(event:Event):void
var swfWidth:int = swfStage.stageWidth;
var swfHeight:int = swfStage.stageHeight;

// Resize the video window.
var newVideoHeight:Number = swfHeight - controlBar.height;
videoScreen.height = newVideoHeight;
videoScreen.scaleX = videoScreen.scaleY;

// Reposition the control bar.
controlBar.y = newVideoHeight;

swfStage.addEventListener(Event.RESIZE, resizeDisplay);

Can this be done and if so how? Thank you in advance for any help given.
