Using a function to change Netstream video size.

Question

Hi folks,
forgive me I am new to script in Flex.  I got an Application that has two scripted functions.  The first is called at creationComplete and sets up a netconnect/netstream video playback.  And a second that is fired when a button is clicked, which sets the application to Full Screen.  What I want to do is resize the video at the same time.  For testing purpose I am using hard coded values that match my monitor size.
The problem I am having is that the code I wrote to change the video size spits out an error "1120: Access of undefined property vid."  - Is it possible to have one function access the vairibles of another function?
My code:
<mx:Script>
        <![CDATA[
            private function initApp():void
                var nc:NetConnection = new NetConnection();
                nc.connect(null);
                var ns:NetStream = new NetStream(nc);
                ns.addEventListener(AsyncErrorEvent.ASYNC_ERROR, asyncErrorHandler); 
                ns.addEventListener(DRMAuthenticateEvent.DRM_AUTHENTICATE, DRMAuthHandler);
                ns.play("gm.f4v");
                function asyncErrorHandler(event:AsyncErrorEvent):void
                    // ignore error
                var vid:Video = new Video();
                vid.attachNetStream(ns);
                vidUI.addChild(vid);
                vid.width=851;
                vid.height=480;
                function DRMAuthHandler(event:DRMAuthenticateEvent):void
                    ns.setDRMAuthenticationCredentials("test","test","drm");
            public function goFull():void
                stage.displayState = StageDisplayState.FULL_SCREEN_INTERACTIVE;
                vid.width=1920;
                vid.height=1080;
        ]]>
    </mx:Script>
I want the function goFull to change the video size that is loaded from the initApp function.... possible?
Cheers!

altering size of text already in a textfield:
var fmt:TextFormat = new TextFormat();
fmt.size = newvalue;
textfield.setTextFormat(fmt)
textfield.defaultTextFormat = fmt; // ensure that text typed after the change is same size
