I can't find any events on my calendar but they show up on mobile me and my iphone.

Hello, I can't find any events on my calendar but they show up on my iphone and mobile me. I see under my lists an aol calendar but I don't see my mobile me. I'm thinking that maybe I had a calendar for mobile me but might have accidently deleted it??? I'm not sure. Can anyone please help? P.S. I'm computer challenged so please speak slowly 🙂
