Thanks. The named range formula seems to do exactly what I was looking for.
I am curious as to what the -- indicates in the formula and how it is used.

The below formula will return the number of primary colors in the array from
Row 1. Adjust the range to suit your requirement..

=SUMPRODUCT(--(ISNUMBER(MATCH(1:1,{"red","blue","green"},0))))

If you are using a named range replace the array with the named range

=SUMPRODUCT(--(ISNUMBER(MATCH(1:1,PRIMARY_COLORS,0))))

I have a row with input data: cells with values of RED, GREEN, PINK, TAN.
I have a table/range (PRIMARY_COLORS) that includes RED, BLUE, GREEN.
I would like to count the number of valid primary colors are in the input
data row.
I cannot figure out how to include a conditional statement in the COUNTIF
function: i.e., COUNTIF the cell value is a MATCH in the PRIMARY_COLORS range.

Can this be done?

Thanks.
