Jumping Issue

I am currently doing a down hill skiing game. I was having issues with my game with the x and y coordinates. To fix these I programmed the game as a horizontal one then I would just simply rotate the entire movie clip to make it seem like the character was skiing down hill. Everything works fine, except, after I rotate the movie clip, the skier will no longer jump, I am guessing it’s the way I programmed the jumping and because once again the x & y are screwed up? I am at a loss.
