How to create an "overview" result slide which resumes 5 previous result slides

I've just built a self-evaluation with a total of 20 items using the quiz templates. The items refer to 5 different "features" (stress, resilience, mindfulness, leadership, salutogenesis) each with 4 items rated on a 4-level Likert scale. To allow participants to self-assess by "characteristic", I have included one separate result slide per "feature" (after 4 questions for each "characteristic)".
-> Question 1: Is it correct to set triggers for the slide levels according to the following model: "Show medium score level when the timeline starts on this slide and when Results.ScorePoints is between 3 and 6"?
I have also inserted a bar/bar chart on the respective slide level and defined the states of the bar using the Results.ScorePoints. So my specific question is: Is it correct to use the Results.ScorePoints to define slide levels and bar states for each of the 5 result slides, or should I select Quiz1.ScorePoints, Quiz2.ScorePoints etc. here?

At the very end, i.e. after all 5 previous result slides, I then installed an "overview" result slide that is supposed to show the results of all 5 previous result slides. So I included 5 bars/one bar chart per “feature” on the results slide. What do I have to align the states of the 5 bars to so that they show the corresponding bar height from the 5 previous result slides? So far (but it doesn't work!) I have defined by Quiz1.ScorePoints, Quiz2.ScorePoints, Quiz3.ScorePoints, etc., . It shows completely randomized bar heights!

I would be extremely grateful for your help and hope that I was able to formulate my questions/problems in an understandable way.

Best regards
