Hi,

Say you have in column A this:

Order No
24
24
24
24
123
123
123
123
123
75
75

and so on. It means that we have 3 orders (i.e., 24, 123, and 75). How
can caculate this? I mean what formula can be used to do so?

Thanks,

Papou,

What if I "Hide" one order number, how do I make the frequency formula
working? Does SUBTOTAL take care of that? If so, what is the "function
number for that?

In the above example, if I hide order # 75, I want the answer to be 2
automatically and so on.

Thanks,
Jo
