I want to count the instances of both "Complete" and "Not Applicable" in the same column. I got it to work with just "Complete" then divide by the total rows to make a percentage using this formula:
=COUNTIF(Status:Status, "Complete") / COUNT(Status:Status)
But when I add the other variable the formula does not work, I have tried
=COUNTIFS([Status]:[Status], "Complete", [Status]:[Status], “Not Applicable”) / COUNT(Status:Status)
and this
=COUNTIFS([Status]:[Status], "Complete" & “Not Applicable”) / COUNT(Status:Status)
