we figured it out!!
Thanks for the replies and the "welcome"! In case anyone runs into this problem, here's the answer. It doesn't give you the option in the menu or anything. You both have to go to the "meeting room". I think that's what it's called. Anyway, once you both are in there, you will see each other and can then go through the game together. Both GBA's must have adapters and the game. Thanks again for the help! I'm sure I'll be back from time to time as they run into more problems.
