Good day!
I have a project that requires a question slide in a form of multiple choice type. Trouble is, the answers requires two valid answers and out of the question there are two possible combination answer. Example:
A B C D E F G where the answer can be either AB or AC only.
I use checkbox widget in combination with the Event Handler and Interactive Master widget by Infosemantics which is good up until the point where the user wants to change his answer. If lets say they clicked on A and B and then decide to go for a different answer (e.g. C and D), they still end up getting a correct answer because they initially clicked AB. I want it to behave as if it was like the multiple choice question slide. I'm not sure if I'm using Infosemantic's widget incorrectly or I need to do some advance action script. Any help is greatly appreciated. Lily? Rod?
