Hi,
I have a data set with 2 columns. One column is filled with names and the other one is filled with numbers.
A B
Name 1 20
Name 1 2
Name 2 1
Name 3
Name 4 2
I would like to count how many unique names that has >0 (empty cell) . In the example above the desired result should be 3 (Name 3 has empty and Name 1 occurs twice).
Thanks
Stefan
