Potty Training My 2 Yr. Old Son

I was wondering if any other moms out there have any advice on how to potty train my two year old. He's showing great interest in the potty, but we're having a very difficult time getting him to understand that he needs to tell us BEFORE he goes potty in his diaper and not after.... any help would be GREATLEY APPRECIATED!!!!!!!!!!
