Sorry @MudMic . You changed how the questions are set up. That is probably your problem. I cannot fix the Lists for you. A huge guess is you entered 2 in this Block; it might require a 6 ???
Here is a version of the original simple checkbox quiz. The aia uses two different text/csv files to provide two question sets. You can have as many question sets as you desire.
Use your own code Blocks and fix them or use the model shown here and not worry about your incorrect Blocks and bug. Have fun.
Unlike your version of the app, this app Works!!! Try the aia please.
