Hi guys, im trying to use CountIFs to count all projects that have a completion date by month. Not all projects are complete so there that are those that do not have an end date has the error #invalid data type".
I tried using this formula, but didn't work. Could I have assistance fixing the formula? If there is an invalid data type, it just wouldn't count that line or return 0 as a value.
=COUNTIFS([Completion Month]:[Completion Month], "January", IFERROR([Completion Month]1, 0))
but I need to do a countifs for all months January-December.
Thanks in advance!
