Help please...I want to count the number of unique values in Column B (delivery postcode) where column I is a specific value (delivery depot) eg how many postcodes did a specific depot deliver to.
I've tried multiple variations of countif, frequency, match etc but can't seem to get it right :( Does anybody have any suggestions?
Thank you
Terri
 

Excel Facts

Shade all formula cells
To shade all formula cells: Home, Find & Select, Formulas to select all formulas. Then apply a light fill color.
Need more info, but try:

=SUM(IF($I$2:$I$15=specific value, (1/COUNTIFS(B2:B15;B2,B15,I2:I15;"="&specific value)); 0))


This is CSE formula.

Sorry, I wasn't being rude, I really appreciate your help. I meant what else would you need to know? I'm happy to share whatever I can for you to help me but don't know what you might need. This is way beyond my Excel ability and even my Google skills are failing me...I'm baffled by the formula not your request for more info.
Both columns B and I have blank cells.
