Forced question order - regardless of which button is clicked.

Thank you Walt and Richard for your quick replies, I truly appreciate it! I've been tasked with creating a Hollywood Squares-esque game. Two people will be sitting together using the same laptop/storyline game, taking turns. There is a third person (a moderator) will be standing nearby. Goofy, I know. 

Ideally: Player #1 will click one of the squares, a question pops up, and under the question will be two buttons: an "X" button and an "O" button. Player #1 says their answer out loud to the moderator. The moderator tells them if they are correct or not. If Player #1 was correct, they click their symbol (let's say that they are the X symbol), and the X symbol appears on top of the square. If they were wrong, they click the other player's symbol (the O symbol) and it appears on the square. 

Then Player #2 takes their turn - if they get it right, they'll click the "O" button so that an O appears on the square. The goal is to get a tic-tac-toe, meaning three squares in a row. This would all be super straightforward to build in Storyline - BUT my client is picky, they want the questions to come up in a specific order, regardless of which square is picked. 

Any guidance you have would be a godsend!

Cheers, 
Leslie
