playing with actionscript

I made a mask over a layer using actionscript like we did and class and i also made it rotate. I tried changing the x and y axis but it got messy. I also tried using multiple keyframes with the x and y, which is maybe why i had problems with that and not the rotation or the masking. i also discovered that once i type comments i must delete both for flash to realize in is no longer a comment? I couldn't erase just one (/) and leave the other for actionscript. I had to delete both retype.
