Snow inside globe

I am making our annual Xmas Card for the library where I work. I am NOT a flash creator… just a paste and cut person. I put together this card and I can’t get the snow to appear ONLY in the globe. All the pieces work and if I have to hear the TEACHER sound clip once more this morning (I’ve been working on this all week) I will run screaming from the building. So… I decided to see the help of experts … that’s you guys! I have included a link to the files.

I appreciate any and all help! V
