Hello Dears,
I have this assignment with 4 factors & 60 Months of the next 5 years
I want to fill the below table to summarize the whole original table by summing all months together in each year
( I used =sumproduct with * , but still I had to choose each 12 columns Manually)
WHAT IS THE BEST APPROACH FOR THIS
