Preload external swf's into one main swf

Forgive me for asking what will probably be a very simple question but I have a nasty headache and I am tired of searching the web for the answer.

Basically I used a tutorial from here to add a preloader to my site. The preloader works for my main swf file, but it does not load the external swf files that I call during the movie playback.

Here is the code I used:


bytes_loaded = Math.round(_root.getBytesLoaded());
bytes_total = Math.round(_root.getBytesTotal());
getPercent = bytes_loaded/bytes_total;
_root.loadBar._width = getPercent100;
_root.loadText = Math.round(getPercent
if (bytes_loaded == bytes_total) {



Because everything already works and is very simple and easy, I was hoping there were a couple of lines I could add to the existing script that would allow me to load external movies as part of the overall loading process.

I have searched and put forth an effort to figure this out but I would really appreciate an experts help at this time.

Thank you
