I am working with two ranges, one contains dates and the other one numbers which I wish to have them added by month such as any number that falls within being >= 01/01/18 but < 02/01/18 gets added. This is what I have thus far:
=SUMIF($[Payment Date]$26:$[Payment Date]$35, AND(@cell >= DATE([Due Date]87), @cell < DATE([Due Date]88), $Forecast$26:$Forecast$35)) This formula returns Zero (Which is incorrect)and this one:
=SUMIF($[Payment Date]$26:$[Payment Date]$35, AND(@cell >= DATE(2018, 1, 1), @cell < DATE(2018, 2, 1)), $Forecast$26:$Forecast$35) returns the correct number.
Can anyone help me understand why the first one is not working?
