Averaging percentage results from 14 exam results scenes " in one field"

Mar 26, 2021

I have built an exam which consists of 14 separate categories, each having a results slide for that category. I also have a menu slide which updates the percentage score for each category as each category scene is completed.

What I want to do is to have a slide which displays the percentage (an average) of the scores% whenever the user jumps to that slide or layer. 

For example if the user achieves 80% in the first category, 60% in the second category and 90% in the 10th category, the "summary" field should display 77%.

This field should change based on the percentage score displayed on the menu slide which may change if the user decides to reset a given category (scene).
