Custom Results Slide - formula for getting a total score from different slides

Hi everyone,

First time in the community and wondering if anyone can help...

I have a custom results slide that I want to pull the scores from 6 slides from to get a 'total'. On each of the 6 slides, I've used a pick one template/form to create the radio button style question options and then depending on what you select, you either get a score of 1, 2, or 3. On each of these 6 slides, I've created three 'Set ScoreS11_1/2/3 equal to 1.00/2.00/or 3.00 if the Radio Button is equal to selected' triggers. I also have a Submit interaction Pick One when the user clicks trigger for my custom submit button.

I'm almost there and thought I almost had it but then, when I run it to se if it's all working how I would like for the results slide, using the below formula,

=%ScoreS11_1%+%ScoreS11_2%+%ScoreS11_3%+%ScoreS11_4%+%ScoreS11_5%+%ScoreS11_6%

I get

0+0+0+0+0+0

rather than just a total between 6-18 depending on the responses provided.

Is there something I can add to my formula to make it total the response from each of the 6 slides?

Thanks so much.
