I am trying to sum 3 different columns and I'm not being successful.
My function is:
=ARRAYFORMULA(SUMIF(MONTH(D:D), 2, A:C))
D is a column with dates, and
C columns with currency (A-value, B-shipping and C-tip). So my idea is to sum the values I got just for the month of February.
The function works but it seems to be just summing the column
A and not the other two. Does anybody know how can I make it sum all 3 columns?
