Topic: "Unattempted quiz questions"

I am still having issues with quiz questions (Presenter sure doesnt make this easy)!!

I have 65 questions in one presentation.  After I publish and start the quiz i keep getting a message that says "there are unattempted quiz questions in this quiz".  when you select "yes" it sents you to the results page of the quiz saying you failed.

This seems to be happening at random points in the quiz.  When i got this message I went to the quiz manager to double check the settings like "if correct answer" and "if wrong answer" and they are both set to "go to next slide".

I have spent 50+ hours formatting and reformatting and when I fix one issue i seem to get another.

Any help would be greatly appreciated!
