I'm trying to have the "NEXT" button become normal when the Learner clicks on all 4 buttons. They should have to click on each button before the "NEXT" button becomes active for them to proceed. Can someone please refer me to a tutorial or offer some advice on how to get this functioning working correctly? I don't seem to understand how the true/false variable works. Thanks for any help I can get. I have attached the project. Each slide layer contains audio and will contain images and text but I haven't gotten that far. I wanted to get the functionality working first.
