Need help on doing the following
Sheet Binc
column J and L
={"$ Per Maand";BYROW(B2:B,LAMBDA(timestamp,IF(LEN(timestamp),SUMIFS(F:F, ARRAYFORMULA(MONTH(B:B)), MONTH(timestamp)),)))}
I have this formula, it is working, but when I make an entry in the last row of 0.0 in column E, it must then make all rows in column J before this value 0.0, and when I add new values, it must then
show monthly values only from the new values
