Hi All-
Hope I can explain this with little confusion. I want to be able to sum the last x data points of unsorted data. For instance, I have two columns
Dates and Units. The dates are entered but they are not in the correct order. Then I have the corresponding units for the dates. I don't want to sort the data because of various reasons. I want to be able to take the last 2 (or x) dates entered and sum the the corresponding units.
