Likert Scale

I just discovered Survey Question > Likert Scale and the associated Survey Results slide. However, I can't figure out how to get it to score a result based on the selections for each question. Also I can't find any tutorials or information in Articulate on this feature. I want to give a score to each selection for each question and then tally the results on the results slide. 

I have been working with this for some time and can't figure out how to accomplish what I need. I've used Rebecca's example here, but it's only one question per slide: https://community.articulate.com/discussions/articulate-storyline/re-likert-scale#143917

I've also tried using a button set for multiple questions on a single page, but that doesn't work either because you can's score each question.

Thanks.
