I have my code (below) , I’m making a preloader to continue to a logo for my website I got errors for some reason:

1120: Access of undefined property loaderF.     removeEventListener(Event.ENTER_FRAME, loaderF);
1120: Access of undefined property loaderF.     addEventListener(Event.ENTER_FRAME, loaderF);

stop();

addEventListener(Event.ENTER_FRAME, loaderF);

function loaderD(e:Event):void{
    var toLoad:Number = loaderInfo.bytesTotal;
    var loaded:Number = loaderInfo.bytesLoaded;
    var total:Number = loaded/toLoad;
    if(loaded == toLoad){
        removeEventListener(Event.ENTER_FRAME, loaderF);
        gotoAndStop(3);
    } else {    
        preloader_mc.preloaderFill_mc.scaleX = total;
        preloader_mc.precent_txt.text = Math.round(total*100) + "%";
        preloader_mc.ofBytes_txt.text = loaded + "bytes";
        preloader_mc.totalBytes_txt.text = toLoad + "bytes";
    }
}
