Quiz review, stuck on hot-spot question during quiz review

During a quiz review, the program is designed to show the PREV and NEXT buttons instead of the SUBMIT button. That built-in functionality doesn't work when you don't use the built-in SUBMIT button.  

You have two options:

• Use the built-in Submit button

or

•  Add the PREV and NEXT buttons to the slide. Program them so they're hidden when the user needs to answer the question, but they show when the user is reviewing the quiz.
  • To do that, you'll need to use a variable to track what the user is doing, plus trigger conditions to hide or show the buttons only during the appropriate times. Here is more info:
