Hi Hannah,
I'm happy to share the steps I applied during the investigation. First, I placed a button on the slide 1.1 that jumps directly to slide 8.8 to make things quicker; it should not affect the outcome of the tests. Then I previewed the project to reproduce the issue. I then removed the variable references and confirmed that they were the ones causing the problem.
Looking closely at the variable references, I checked if the variables were the ones being used by looking at the other Result slides. True enough, incorrect variables proved to be the cause of the issue.
Since the project contains a lot of slides, putting a button on the first slide that jumps directly to the affected slide is always a good idea!
