How can I put a text preloader into this code?

Hi

I've been working on a site where swf's are loaded into main movie with transitions between the sections. I have the following code on the mcContainer...

onClipEvent (enterFrame) {

 if (!loaded && this._url != _root._url) {

 if (this.getBytesLoaded() == this.getBytesTotal()) {

 loaded = true;

 _root.transition.gotoAndPlay("opening");

 }

 }

}

How can I add a text percentage preloader into this code?

I usually use a the following code for preloaders...

myLoaded = Math.round(getBytesLoaded());

myTotal = Math.round(getBytesTotal());

myPercent = myLoaded/myTotal;

myBar._height = myPercent*97;

myText = Math.round(myPercent*100)+"%";

if (myLoaded == myTotal) {

 gotoAndStop("Scene 1", "loaded");

} else {

 gotoAndPlay("Scene 1", "preloader");

}

... but I'm not sure where to add the code into the exisiting code, as I'm a beginner at AS.

Any help will be greatly recieved.

Thanks
Wayne
