Mask Question/Problem

OK I attached 2 jpegs to help explain this…lol…

jpeg1…

Im trying to create a little animation…the background is an animated movie clip…it just shifts between transparencies of the same pic changed a bit from one to the next…

i created the movie clip “back” then masked it with a shape thats the same as the red border…ive aslo got the mask masking the branch a bit…

on screen there everything shows up…but when i test the movie the back ground doesnt show up (jpeg 2)…the branch does…? Im confused…lol…

any ideas? tia…

actually im trying to move its position around in the layers and its not wanting to show up at all when i test the movie? Im stumped…
