Mask preloader problems

Hey all. I’ve got (what should be) a simple problem with my preloader: I am using a mask as the loadbar, so that the object mask increased proportionally to the amount loaded. I made the same effect using a tween here www.lg-ac.com/sewnsew/tweened.html - but it didn’t work for me as a preloader as can be seen at www.lg-ac.com/sewnsew/preloader.html . I am probably missing something really simple, but if anyone has time check out my source www.lg-ac.com/sewnsew/preloader.fla

As always, thanks :slight_smile:
