Hello,




I have a large table of more than 2000 rows, and 5 columns. The values of these cells are either 1 or 0. For each column I want to be able to count the number of 1s in blocks of 20 rows starting from the first row. Example: For each column count the number of 1s in the first 20 cells (A1:A20), then in cells 21 to 41 (A21:A41), then from 42 to 62 and so on. Any help is appreciated.


Many thanks,
egit
