You can use an array formula** like this:

=SUM((IF(A1="total",ROW(A5:A20)^0,A5:A20=A1))*(B5: B20=B1)*(C5:C20=C1)*D5:D20)

** array formulas need to be entered using the key combination of
CTRL,SHIFT,ENTER (not just ENTER). Hold down both the CTRL key and the SHIFT
key then hit ENTER.

I am using Sumproduct with three variables (Person, Product and Month).

I am using data validation lists for the end user to select the person,
product and month. I would like to be able to add a "Total" to the person
list so that when the end user chooses "Total" and a product and month
that
the Sumproduct would only use the two other criteria (Product and Month)
and
be able to see the totals of those criteria for all Persons.

I know I could nest IF THEN statements with the Sumproduct, but is there a
better way???

Appreciate the help!
