I have this problem where i will put an image on one layer over 15 frames, then on the top layer i will draw a square, make it a symbol, tween it over 15 frames with the shape tween with the alpha set to 0% on frame 1 and 100% on frame two, and i set that to mask and when i test the movie, it just pops the image up without the alpha tween acting as a mask. Am i doing something wrong? As far as i know this should work, but it’s not.

Thanks for any help offered.
