Nevermind. I figured it out. I forgot to make sure View Quiz Information was set to Allow. I had it set up so they could attempt the quiz, but not actually see it. Happens when you stare at the permissions for 3 hours straight. haha. Thanks anyway.
Having the exact same problem. Where are the 'visible' settings? Please and Thank you.
Under Quiz Admin, I DO have the visible parameter set to Show.
