Help with a preloader in AS3

Hi,

I upload a website and I have problems with the preloader did it in AS3. It starts after two or three minutes. I have a MC with an animation of 100 frames and the dynamic text of the percent. The preloader is located in the 1 frame to the 10, I mean, first frame with the actions and the other three layers (text, MC and background) with a lenght of 10. The movie has 525 frames. Here is the code:

stop();

addEventListener(Event.ENTER_FRAME, lodeando);

function lodeando(event:Event):void

{

          var bytesTotales = stage.loaderInfo.bytesTotal;

          var bytesCargados = stage.loaderInfo.bytesLoaded;

          var porcentaje = Math.round(bytesCargados * 100 / bytesTotales);

          textoPorcentaje.text = porcentaje + "% Cargados";

          cargaAnimada_mc.gotoAndStop(porcentaje);

          if (bytesCargados == bytesTotales)

          {

                    removeEventListener(Event.ENTER_FRAME, lodeando);

                    gotoAndPlay(2);

                    textoPorcentaje.text = "";

                    removeChild(textoPorcentaje);

                    removeChild(cargaAnimada_mc);

          }

}

Please, Could you help me?.
