If those values that are returned are really the Boolean TRUE and FALSE, then
remove the double quotes:
=SUMPRODUCT(--(b3:b383=FALSE),--(E3:E383=FALSE))
or
=SUMPRODUCT((CZ3:CZ383=FALSE)*(E3:E383=FALSE))

But excel will treat empty cells as FALSE.

You may want something like:
=SUMPRODUCT(--(b3:b383<""),--(b3:b383=FALSE),
--(e3:e383<""),--(e3:e383=FALSE))

Adjust the ranges to match--but you can't use whole columns.

=sumproduct() likes to work with numbers. The -- stuff changes trues and falses
to 1's and 0's.

Bob Phillips explains =sumproduct() in much more detail he

Hi, the answer to my problem is pobably obvious but i need help.

I have a database in which column B returns True or False values and
column E returns true or false values .

I would like to count the number of cells in which False appears in
both columns in the same row, ie if b4 and e4 are both false, then it
returns the value 1.

The range is from rows 3 to 383.

I have tried these formulas but they keep on returning 0.

=SUMPRODUCT((b3:b383="FALSE"),(E3:E383="FALSE"))

=SUMPRODUCT((CZ3:CZ383="FALSE")*(E3:E383="FALSE")) .

your help would be gratefully appreciated.
