I'm trying to create a mask by copying and pasting an image I made in Illustrator. The times this has worked seemed erratic and random. Most of the time the image comes over and the mask is applied, but nothing is masked out. I took a screenshot of what's going on.

The mask of the jellyfish is on, but the solid hasn't been masked out. It's just on top of the solid... I'm not sure why this is happening.
Can anyone help me?
