Problem preloading numerous swf's

This should be very easy for most of you

im trying to load one swf with its own preloader, wait till its loaded then load another.

i was going to load it like this, with nested if statments:

preloader_mc.loadMovie(“img1.swf”,90);
if(preloader_mc.getBytesLoaded() == preloader_mc.getBytesTotal()){
preloader_mc.loadMovie(“img2.swf”,90);
}

but i cant seem to get it to work.

trace(preloader_mc.getBytesLoaded()) returns 4
trace(preloader_mc.getBytesTotal()) returns 4

before it loads the first swf, so it fails right off the bat.
can someone help me. im in kinda of a bind.
