How does Cumulative Sum work with RangeSum and Peek in script editor?
this a bit different question: I found a script showing how to calculate a cumulative sum in load editor using RangeSum() and Peek(). Although I know both these functions I can't understand how they work together and return a proper Cumulative Sum. Can someone explain me how Peek() works as an argument in RangeSum()?
The concept is:
RangeSum(value,Peek(CumulativeSum)) as CumulativeSum
