Try

=SUMPRODUCT(--($B$4:$B$97="Yes"),--(MOD(ROW($B$4:$B$97),3)=1))

adapt to fit your range

How do I include multiple non-consecutive rows in a COUNTIF function. I
need
to check rows (4,7,10,13 thru 97 (every third row)) for a value. I used
=
COUNTIF (4:4, "Yes") and it returns the correct number. I have tried
several
methods to include the 32 row I need to check for the value "Yes" and it
will
not allow the multiple rows

Thanks in advance.
