Hi, I have a x 2 table like this:
Rows can vary from 1:inf.
I need sum of the monthly Turnover (2. column) from timestamp (1. column) (last row is latest time and the "anchored" timestamp - means i need turnover 1 month prior that latest time in the bottom). Anyone know a way out of this? Keep in mind if there is no full month in 1. column (there could be only, say, 3 rows) then I need the sum of it all.
