Preloaders within a Movie

Hi, this might be a very simple one!

I just can’t work it out. I am trying to open a movie within another movie, but can’t seem to get the preloader in the second movie working.

total_bytes = _root.getBytesTotal();
loaded_bytes = _root.getBytesLoaded();
remaining_bytes = total_bytes-loaded_bytes;
percent_done = int((loaded_bytes/total_bytes)*100);
bar.gotoAndStop(percent_done);
ifFrameLoaded (“Scene 2”, 350) {
gotoAndPlay(“Scene 2”, 1);
}

I have used the code above for both movies. This all works fine on the first movie.

When i select a button from the navigation area to open a new movie on the right handside preloading bar don’t seem to move.

any suggestions are welcome.

Only the trends and ranges buttons work.
