Preloader for external swf load

programming flash
1

I have my main swf file and two external swf files i’m trying to load into the main one. I have preloaders for each external swf file but when I have the main swf file it won’t load the preloaders it seems to be loading the entire thing and then showing the swf. How do i change that to showing the preloaders i already have?

here is my code at the beginning on each external swf, I don’t know that much about actionscript so any help would be greatly appreciated.

stop();
myBar._width=0;
preloadI=setInterval(preloadF,100);

function preloadF(){

fractionLoaded = getBytesLoaded()/getBytesTotal();
myBar._width = fractionLoaded212; // i’m not sure about that 408, but you can check that.
myText = Math.round(fractionLoaded100)+"%";

if (getBytesLoaded() == getBytesTotal()) {
clearInterval(preloadI);
gotoAndPlay(3);
}

}

here is the code to call and load the external swf

myContainer.loadMovie(“rambovid.swf”);
