Scoring - Rating Selector Field
Make sure you substitute the $fieldkey$'s in the example code, with your own form's $fieldkey$'s. The code below is what you will be putting on your computed label.
integer($rating1$) + integer($rating2$) + integer($rating3$);
You will add additional "integer($fieldkey$) +..." for however many rating fields that you have.
In the above example, I have three rating fields and a computed label with the code placed inside.
This is what it looks like in the app.
