Create a Sum of Multiple Fields

Hi Guys,

So I am working on a CMS for an NGO. There is a custom module I created - DLA (Daily Living Activities), which have the staff rate their candidate’s emotional status based on a few standard questions. All of the fields in the module use the same dropdown menu. How can I sum up all of these values so I get a final score/rating.

I have attached a screenshot for your review.

So as you see, there are about a dozen questions and all of them have the same dropdown option. I need to create a workflow where the system calculates the sum of all the answers and divides them by 2.

Can anyone please help me with this?
