Yeah! If you're familiar with Javascript, I can walk you through it! We had a similar situation come up earlier on the discussion board.



Are you familiar with JS?

Thanks a lot Micheal. I am a bit familiar with JS. Will be happy to have a discussion. What's the best way we could connect?

For sure! I'm trying to post my answer, but I'm having issues on my end.. one sec.

I think this discussion board is fine - I want to make sure this solution is available to any others who are searching for it later, but if it gets too complex or involved, I can DM you!



If you're familiar with jQuery, you can do the following (I'm going to explain it conceptually, and if that doesn't do the trick, we can dive into the actual code. Don't be concerned if you don't understand, but I encourage experimentation and engaged learning so you can adjust to the platform through the process).

- Put an `.on('change' () ={})` listener to those captured fields

- When the `change` method is called, then get the sum of the fields, and then update the value of your display.



Here is some sample code (not usable in the API)



Let's say your matrix question rows have a class` 'matrix-row'`, and your Display field has an id of 'sum-display';



You would go like this:

Hm... it won't let me post the code snippet...
