Toggling between text boxes

[wardma]

Hi I'm making a noughts and crosses game. In each of the squares there are four text boxes, one on top of the other. The top one has the question, the next is the answer, the next is a "O" and the bottom one is "X". It's for my maths kids. If I click the top box it disappears (yay!), click on next one it disappears (yay!). I'd previously had the third one ("O") set up to disappear so the the one is the "X" but I want to then be able to come back to the "O" if I stuff up in class and make a mistake (so I don't have to jettison the whole game). So... I really want to have the "O" visible, disappear then come back if needed. It's like a loop. Ideas? Thanks
