Quiz scoring

Hi

I am new to quizzes on storyline 2.  My client has 15 scenes in 1 course.  At the end of each scene they want a short knowledge check - which I have built.  Each scene also has its own results slide.  The last scene is just a results slide for the entire course.

The problem is that now that I have brought all these scenes together the scene quizzes will show pass/fail on the their individual results slides but the score always is "0%".

Isn't there a way that it can show an actual score on each scenes results slide?

Thanks for any help!!
