Likert survey feedback by result bracket

Hi all,

I'm trying to create a results slide based on a 2-slide, 20-question survey. I would like to show different layers based on the learner's input from the survey. Basically, if their total points from the survey is: 

• 0-20 --> show layer 1
• 21-45 --> show layer 2
• 46-60 --> show layer 3

I've used the %Results.ScorePoints% variable to setup the conditions to show the layers. However, Storyline doesn't appear to be capturing the user input. It always reverts to "0 points".

Am I going about this wrong? Is this variable only usable in a graded quiz and not a survey? If not, is there another way to do this with a survey? I've seen other tutorials do this with multiple-choice questions, but I can't ask the learner to click through 20 slides for the survey.

This seems like a basic ask for a course. Any help would be very much appreciated.

Thanks!
