I am trying to calculate a cumulative total of [payments], but I want it to sum in ascending order of [day]. All solutions I have found start the running total with the largest payments down to the smallest. I want the cumulative total from day 0 - x. Thanks in advance.
Update: Your solution works. I tested it on a smaller dataset. But, since it takes too long to load on my dataset, I have made an adjustment to my [Day] column. It is now a text field with less values. Can you modify your solution to work with a text field column please? Thank you in advance for all your help.
