I have a learner that's stuck on a quick quiz. He gets all of the questions right, but it marks him as scoring Infinity% (30 points). The passing score is listed as 100% (0 points) in the course. However, in the storyline file, everything looks correct and the quiz functions perfectly. No one on my team has ever seen this, and we're truly at a loss. Any ideas?
