Hi,
This is to seeking help how to sum the "Down Payment" & "P.G. Billing 1" when Due Date are JAN.2019, Pls refer to the attached picture.
I'm using the below formula for single column computation,
=SUMIF([Due Date 1]16:[Due Date 1]24, "JAN.2019", [Down Payment]16:[Down Payment]24)
But have no idea how to sum within multiple column.
