HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

okay. i'm really hating imageready right now.

i'm trying to do a minimovie. and i've got everything setup. the animation bar looks like this:


(or at least the beginning)

HOWEVER when i play it....the transparent part won't go trasnparent.the checkered boxes stay and that's not how i want it. so i have to copy and paste the stupid background in every single frame and that makes the animation even bigger in size.

could anyone pleaseeeeeeeeeeeeeee tell me how to fix that! broomsticks and i are about to tear our hair out.
