Preloader Help

gonna try to explain this…

i would like to have a preloader run in a movie clip rather than in the main scene…

i have followed this tutorial exact and it works when i create it on the main scene,

but the loading bar and text doesnt work when i build it in a movie clip

is there more actionscript needed to make it work, different way, is it possible?

thanks
