Count number of people across multiple columns wit

问题:

Here is the original question:

Count number of people across multiple columns with criteria

Original formula:

=COUNTIF(C3:F3,">" & DATE(YEAR($B$1)-20,MONTH($B$1),DAY($B$1)))

I am looking to modify the formula to count ages >= 21 and <= 24.

Here is what I have tried:

=COUNTIF(INDEX(C3:F3),"<="&DATE(YEAR($E$4)-21,MONTH($E$4),DAY($E$4)&">="&DATE(YEAR($E$4)-24,MONTH($E$4),DAY($E$4))))

Any help is must appreciated!

Your COUNTIFS is wrong. You need to put the range twice not use & to add criteria:

=COUNTIFS(C3:F3,"<="&DATE(YEAR($E$4)-21,MONTH($E$4),DAY($E$4)),C3:F3,">="&DATE(YEAR($E$4)-24,MONTH($E$4),DAY($E$4))))
