Hi,
If I use the array formula bellow to count the unique values of a list
it works fine.
{=SUM(1/COUNTIF(C8:C11,C8:C11))}
But what I really need is the sum of unique values, of each subset of
the list.
A B
1 dog 1
2 dog 1
3 dog 3
4 dog 2
5 cat 1
6 cat 2
For example if I have the table above, the result that I want is the
sum of 3 different of dog subset elements plus 2 from cat subset.
Anyone can help me?
Thanks,
Ricardo
Thanks a lot, It's does exactly what I'm looking for.
HKaplan, I dont want to sum dog elements, I was trying to count unique
values. Sorry my bad English if you don't understand.
You're welcome. Thanks for the feedback!
