Help with flags on multiple GUI

Hello,

I'm currently trying to create a who wants to be a millionaire type game complete with lifelines. I have a GUI for each question and I was wondering how I can disable a lifeline if one has been used in a round and make this remain in the other GUIs?

Thank you!

See the FAQ for ways you can share your array of flags between different functions or different gui figures: http://matlab.wikia.com/wiki/FAQ#How_can_I_share_data_between_callback_functions_in_my_GUI.28s.29.3F
