preloader that corresponds to movie clip

[Matokist]

right, ive spent several days trying to work this out and now I have to accept that im going to have to start another preloader thread and be hated.

I want to make a preloader that corresponds to a movie clip.

the movie clip is 100frames long and is my logo filling up with colour from the bottom up. each increment in colour = 1 frame = 1 percent loaded. its called 'preloader'

so i go back to scene 1. ive got 2 layers

actions
movieclip

what do I do now, everytime ive progressed from this point ive gone wrong.

thankyou to anyone who can lend me their help.

ok, so ive been trying out code but it still wont work.

ive got my two layers actions and preloader.

in frame1 of action layer I ahve this:

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);
if (percent_done>99) {
gotoAndPlay("Scene 2", "1");
}

and in frame2 I have:

gotoAndPlay(1);

my movie clip is called bar and has 100frames with a stop at the start.

but still no joy. any advice?
