A Solution to rounding in Storyline – without using Javascript

I can't get this to work. I used the file that Tom uploaded four years ago (thanks Tom)! Wonder why this is still not automatic.

Anyway, maybe it's not working because I have two quizzes in my course so I have two results slides + I also have a final results slide.

I'm not as technically inclined as most of you so I just literally copy everything that Tom did in his file. I am unable to troubleshoot with my low skill levels. 

Can anyone help me figure out why it isn't working? Does it have to do with the fact that I have 3 results slides? Should one of the triggers be altered? Do I need 3 variables...1 for each results slide? Everything I've tried has failed.

Thanks!
