Hi All!

I am trying to get an mp3 to start streaming after a jpg has finished dynamically loading. I know the best way to do this is to use MovieClipLoader.onLoadComplete(), however I’m having a few implementation problems as you can see below. Any help would be really appreciated.

```auto
function nextImage() {
	 if (p< (total-1)) {
		 p++;
		 if (loaded == filesize) {
			 empty_mc._alpha = 0;
			 mclListener.onLoadStart =function(empty_mc) {
					empty_mc.loadMovie(image[p], 1);
			 };
			 mclListener.onLoadComplete =function(empty_mc) {
					audio_mc.loadSound(audio[p], 1);
			 };
		 }
	 }
}

```

Thank you.
