The following formula counts the number of non blank cels in row e,

I doubt that formula would work at all.


I also want to NOT add any cell that has a duplicate reference number
in column c.


dress sheet:

a b c d e
dept color style name units
331 blk 1 12
331 blk 2 12
331 blk 2 12
332 blk 4 12
332 blk 5 12
332 blk 6 12
332 blk 6 12
332 blk 7 12


On the summary sheet for dept 331, the answer should be 2
Because there are 2 unique styles - style 1 and style 2 in dept 331.

I assume I have to add to my existing formula


If you download and install the morefunc.xll add-in:

=COUNTDIFF(IF(A2:A9=331,C2:C9,0),FALSE,0)

which you need to confirm with control+shift+enter.
