Linking GUI in MATLAB

I am trying to program a game of tic tac toe in MATLAB I have 3 GUI setup. The first one asks the player to choose "X" or "O", the second, asks who wants to go first "player" or "computer" and the third is the board. How do I link the three and code matlab to remember the choices?

Why make your UI complicated by having three separate GUIs running? Just make one full screen GUI and put all your buttons and things on that. It will also be a lot easier to communicate between functions.

If you still want to do it this klunky, more complicated way with multiple GUIs then see the latter part of this FAQ entry: http://matlab.wikia.com/wiki/FAQ#How_can_I_share_data_between_callback_functions_in_my_GUI.28s.29.3F

Thank you for your reply and you're right. I think I'll do that but I'm finding it harder to show images for x and o depending on who's turn it is and whether it's x or o.
