Hi Guys,

I have a column A with names and column B with dates.


I would like to have a formula that a can place in any other column
that will count how mnay unique dates are ther for a specific name.


For example if i have John Doe in A as one of the many names the
formula should tell me how many unique dates are there for John. With
in the many repeated dates that John may have, those dates should be
counted.


Example:


A B C
D E

DAYS
JOHN DOE 27-Sep JOHN DOE 3
JOHN DOE 27-Sep TINA DOE 3
TINA DOE 27-Sep CARL DOE 4
CARL DOE 27-Sep
CARL DOE 27-Sep
JOHN DOE 28-Aug
TINA DOE 29-Aug
TINA DOE 29-Aug
TINA DOE 29-Aug
CARL DOE 30-Aug
JOHN DOE 29-Aug
TINA DOE 30-Aug
CARL DOE 31-Aug
CARL DOE 25-Sep


Hope some one can help.... THNX
