I am trying to adjust some formulas we have for budgeting replacement computers. The sheet references another sheet and previously was just counting based on a date range to count computers due for replacement. I now wanted to expand this out further and use it to count Windows replacements and Mac replacements. I need the formula to count from a dropdown if the OS field meets "Windows 11 Professional" OR "Windows 11 Enterprise" from the source sheet. I am finding that it will count one or the other just fine but struggling to have it count if it is matching one or the other. The formula I am trying is:
=COUNTIFS({MEDC Active Computers Rec'd Date}, >=DATE(2021, 9, 1), {MEDC Active Computers Rec'd Date}, <=DATE(2021, 9, 31), {MEDC Active Computers OS}, "Windows 11 Enterprise", {MEDC Active Computers OS}, "Windows 11 Professional")
I think I need to make the last two statements an OR in some way to have it count correctly.
