Calculating Sum from List

Actions & Logic

I have a collection Lessons for which I need to calculate the Overall Score from a List<Doc Reference(Results)> to display on the Score Card. How can I do that?

What have you tried so far?

I have tried to update documents from the Lessons collections when the Results document is created by incrementing the values, but its not working. I tried to implement code expression, but not sure if that was correct. I was looking at adding custom function, but have not clue as to what argument I should add, and the once I tried didn't seem right. Would appreciate help. Thanks.

Did you check FlutterFlow's Documentation for this topic?

Yes
