Different groups of Tick Boxes?
I have slide that requires 3 groups of 3 tick boxes.
The user can only tick 1 box in a group of 3. If they tick a different box of the same group, then the other box that has been ticked goes blank. One one box can be ticked in the group.
I require three groups. The answer will be submitted as correct when the user has chosen the correct tick box from each group.
Apart from having to probably create dozens of triggers, is there a simple way to achieve this ?
