preloader script not working in MC

Hi
I have made the next script an put it in the first frame of the stage
it's works fine but if i put it in a MC the progressBar will not work.
Here is the text:

code:

---

stop();

myInterval = setInterval(preloader,10);

function preloader() {

    if (getBytesLoaded() >= getBytesTotal()) {

        play();

        clearInterval(myInterval);

    }

    progressBar._xscale = (getBytesLoaded()/getBytesTotal())*100;

}

---

I have tryed many variation change the play(); with "_root.play",or with "with _root.play..","_root.getbytes..." and so on but i cant make the progressBar work , can someone help me here

Thank you very much..

is the progress bar in the MC or on the stage?

**edit..also, why does it need to be in a MC?

The progresBar is a MC with 1 frame were the loading line is.
I just wanted to put progressBar mc, the loading text mc and the animation mc in one Mc(preloader) and if i will need a preloading again in another fla i will just copy the preloader mc into the new fla.

Thanks

Well, assuming the script is inside an MC, and that_root is the thing you need the preloader for, then:

you'll need to put a stop(); in frame 1 of _root or add this line:

_root.stop();

(the stop() in your script isn't going to stop the main timeline).

you'll need to use _root.play();

and you'll need to use

_root.getBytesLoaded() instead of getBytesLoaded()

and _root.getBytesTotal() instead of getBytesTotal()

in your current example, you have essentially written a preloader for your little preloader MC - anything that needs to refer to _root (or the parent clip) needs to be adjusted.

I tryed with _root.play();but not with _root.stop();
Thank you very much for the help, now its working:)
