Simple problem with TypeError: Error #1009

programming flash

Hello to all the talented people at Kirupa!

I’ll make this as simple to follow as possible, as I really need your help!

My document is laid out as follows.

Frame 1: Preloader.
Frame 2: Game content.
Frame 3: Game content.
Main class: Game.as.

I had everything on Frame 1 (Preloader, Game content) and Frame 2 (Game content) but I have changed it and inserted a new frame (which is now Frame 1) for just the preloader (This was because a long white screen was appearing before the preloader came on).

When I export and preview the game, I get TypeError: Error #1009 on any line of code that references a movieclip that is on Frame 2 (regardless of whether or not it has an instance name).

Here is some code:

 
       public function Game()
        {
            stage.showDefaultContextMenu = false;
            main = this;
        
            if(this.loaderInfo.bytesLoaded < this.loaderInfo.bytesTotal)
            {
            loaderInfo.addEventListener(ProgressEvent.PROGRESS, progressHandler, false, 0, true);
            loaderInfo.addEventListener(Event.COMPLETE, completeListener, false, 0, true);
            }
        
        public function progressHandler(e:ProgressEvent):void
        {
            loaderBar.meter.scaleX = e.bytesLoaded / e.bytesTotal;
        }
        
        public function completeListener(event:Event):void
        {
            loaderInfo.removeEventListener(ProgressEvent.PROGRESS,progressHandler);
            loaderInfo.removeEventListener(Event.COMPLETE,completeListener);
            
            gotoAndStop(2);
            
            stage.addChild(teslaMovie);        
            teslaMovie.gotoAndPlay(1);
            
            settleIn();
        }
        
        public function settleIn()
        {
            /*    ERROR HAPPENS HERE: MCs given instance names on Frame 2:
            
            playNowButton.visible = false;
            mcIntroBg.visible = false;
            mcLogo.visible = false;
            mainMenu.visible = false;
            LevelSelect.main.visible = false; */
            
            debrisOn = true;
            lightingOn = true;
            backgroundOn = true;
            musicOn = true;
            
            //Pause.main.init();
            Key.initialize(stage);        
            
            mcIntroBg.visible = true;
            //mcLogo.visible = true;
            
            //playNowButton.buttonMode = true;            
            //playNowButton.visible = true;
            //playNowButton.addEventListener(MouseEvent.CLICK, showMenuOptions, false, 0, true);
        }

Note that mcIntroBg.visible = true; is referencing an MC on frame 1, so it is fine. Do I really have to place all my movie clips onto the stage on frame 1 to get rid of this problem or is there an easy solution that I am missing??

Thanks in advance, Harry.
