Hello everybody.

I've a situation like the following:

column f column g
A ONE
A ONE
A TWO
A THREE
A THREE
B ONE
B ONE
B ONE
B TWO
A FOUR
A FOUR
A FOUR
A FOUR
A FIVE

I need a formula that counts how many differents values in column g for the value A in column f (in the example 5) and how many different values in column g for the value B in column f (in the example 2).

Thank you.

Many thanks for the support: it works perfectly well.

Just add a constraint, if possible: to exclude the rows with value 0 in column h

column f column g column h
A ONE 7
A ONE 5
A TWO 0
A THREE 4
A THREE 2
B ONE 3
B ONE 0
B ONE 5
B TWO 6
A FOUR 0
A FOUR 2
A FOUR 4
A FOUR 3
A FIVE 2

Thank's: until today, it seems ok.

Now, I'm going to study the structure of the formula.
