Using your posted data, try this: E1: =SUMPRODUCT((A2:A15<"")/COUNTIF(A2:A15,A2:A15&"")) Does that help?

=SUM(IF(FREQUENCY(MATCH(NAME,NAME,0),MATCH(NAME,NA ME,0))0,1))
this could be used on each column or you could use a helper column where the NAME and LASTNAME are added together.

If you download and install the morefunc.xll add-in...
=COUNTDIFF(CodeRange,,"") Otherwise... Either: =SUM(IF(CodeRange<"",1/COUNTIF(CodeRange,CodeRange))) which needs to be confirmed with control+shift+enter. Or: =SUMPRODUCT((CodeRange<"")/(COUNTIF(CodeRange,CodeRange&"")) louisp wrote: hello, Here is a sample of data that I have: CODE NAME LASTNAME TS19 Sylvain Brook TS19 Sylvain Brook TV04 Valérie Musoni TV04 Valérie Musoni VB05 Ben Valiquette VB05 Ben Valiquette VB05 Ben Valiquette VI02 Isabelle Vanasse VR07 Richard Vivo VR07 Richard Vivo VR07 Richard Vivo WD01 Dany Williams WD01 Dany Williams WD01 Dany Williams How can I quickly get the total number of employees from a list like this one? the first field is a unique key (1 code per employee) In this case, the desired result would be 6.

Ron, that is brilliant. I don't know if my opinion means anything to you,
but I am extremely impressed. "Ron Coderre" wrote: Using your posted data, try this: E1: =SUMPRODUCT((A2:A15<"")/COUNTIF(A2:A15,A2:A15&"")) Does that help?

Thank you everyone for the replies. I have to admit that I do not fully understand what the sumproduct/countif function does.. Does the sum of specified products, then divides by the amount of non-empty products? I like the countdiff function.... will have to try it out. Hooray for simplicity! thanks again... louis -- louisp ------------------------------------------------------------------------ louisp's Profile: http://www.excelforum.com/member.php...o&userid=25880 View this thread: http://www.excelforum.com/showthread...hreadid=511929 |

Sloth, =SUMPRODUCT((A2:A15<"")/COUNTIF(A2:A15,A2:A15&"")) I agree that the formula is brilliant, but I can't take credit for inventing it. I'm sure I saw it some time ago in the MS Excel newsgroups and copied it into my trove of "must have" solutions. I hope whoever DID invent it sees your compliment and this reply and takes some satisfaction in knowing that they did the Excel-using population some good.

Hi, Aladin
I just read the links you posted. Thanks for giving us the count-unique formula's pedigree. And kudos to you and Harlan for coming up with that solution. *********** Best Regards, Ron XL2002, WinXP-Pro "Aladin Akyurek" wrote: louisp Wrote: Thank you everyone for the replies.
