Count unique values based on criteria

[GraceF]

Hello

I am trying to work with the data below, to count the unique number of values in column B, when column A meets a certain criteria.

<TABLE style="WIDTH: 96pt; BORDER-COLLAPSE: collapse" cellSpacing=0 cellPadding=0 width=128 border=0 x:str><COLGROUP><COL style="WIDTH: 48pt" span=2 width=64><TBODY><TR style="HEIGHT: 13.5pt" height=18><TD class=xl22 style="BORDER-RIGHT: #d4d0c8;

For each division A to E, I would like to know the number of unique employees and would expect to get the results below:

I have figured out how to count the number of unique numbers (=SUM(IF(FREQUENCY(B5:B15,B5:B15)>0,1))) but I can't work out how to tie this into being dependant on the division.

Any help would be much appreciated!

Thanks
Grace

Hi Grace,

Welcome to the board.

Try this:

=SUM(IF(FREQUENCY(IF($A$5:$A$15=RIGHT(D5,1),$B$5:$B$15),$B$5:$B$15)>0,1))

This is an Array formula, you must confirm the entry with CTRL+SHIFT+ENTER, not just Enter.

Where:

A5:A15 is your data that holds the Division Letter, B5:B15 is your data that holds the employee ID and D5 is your Division Name (Division A for example).
