Preloader with transition help

i think im actually going to go crazy if i dont figure this out soon

i followed a tutorial i found on a forum about how to make a preloader with a simple transition

http://board.flashkit.com/board/showthread.php?t=597084&page=2&pp=20&highlight=preloader

ive built it…
but seems that the preloading bar doesnt really listen to the getBytesLoaded thing and sort of just plays through the animation

im sure its probably something simple or im just being stupid and cant see it as im a bit of a n00b to actionscripting
ive atached the file and if anyone can help it would be very much apreciated

thanks in advance
