Hi, I'm trying to get a count of unique values in column B when criteria matches for columns A,C and D. The worksheet I'm trying to complete looks like this:

2366 2005 T [number of corresponding unique values of B]

For example:

--D---C---A-B
2366 2005 T 2
(as opposed to 3)

Any advice would be greatly appreciated!



<table style="border-collapse: collapse;" width="215" border="0" cellpadding="0" cellspacing="0" height="564"><col style="width: 30pt;" width="40"> <col style="width: 47pt;" width="62"> <col style="width: 27pt;" width="36"> <col style="width: 47pt;" width="62"> <tbody><tr style="height: 63.75pt;" height="85"> <td class="xl65" style="height: 63.75pt; width: 30pt;" width="40" height="85">A</td> <td valign="top">

Thanks all. Domenic, I get a NA error with that function. I may be doing something wrong.

=SUM(IF(FREQUENCY(IF($A$2:$A$14="T",IF($C$2:$C$14=2005,IF($D$2:$D$14=2366,IF($B$2:$B$14<>"",MATCH("~"&$B$2:$B$14,$B$2:$B$14&"",0))))),ROW($B$2:$B$14)-ROW($B$2)+1),1))

Here is a better example of what I'm working with if anyone would like to take a stab.
A B C D
F 1655 2005 505
F 1656 2005 505
F 1656 2005 505
F 1659 2005 505
F 1659 2005 505
F 1659 2005 505
F 1659 2005 505
F 1660 2006 505
F 1660 2006 505
F 1660 2006 505
F 1660 2006 505
T 437 2006 918
T 437 2006 918
T 437 2006 918
T 461 2007 918
T 461 2007 918
T 461 2007 918
T 461 2007 918

T 464 2007 918
T 466 2007 918
T 466 2007 918
T 466 2007 918
T 469 2007 918
T 469 2007 918
T 469 2007 918

D A C Number of unique occurances of B
505 F 2005 3
505 F 2006 1
918 T 2006 ?
918 T 2007 ?


Thanks!

Excel Facts

Enter current date or time
Ctrl+: enters current time. Ctrl+; enters current date. Use Ctrl+: Ctrl+; Enter for current date & time.
Did you confirm the formula with CONTROL+SHIFT+ENTER, not just ENTER?

Perhaps,
=SUMPRODUCT(--(A1:A13="T"), --(C1:C13=2005), --(D1:D13=2366), 1/COUNTIF(B1:B13,B1:B13))
Click to expand...

When I use Mike's formula in the following manner, the result is 130.5.

=SUMPRODUCT(--(INDEX(Consolidated,0,16)=G25),--(LEFT(INDEX(Consolidated,0,15),2)="PR"),--(MONTH(INDEX(Consolidated,0,24))=MONTH($B$1)),--(INDEX(Consolidated,0,4)="C"),--(MONTH(INDEX(Consolidated,0,14))=MONTH($B$1)),1/COUNTIF(INDEX(Consolidated,0,1),INDEX(Consolidated,0,1)))

Can someone explain this please.

I used an almost identical formula I found from an ExcelIsFun YouTube video:
Code: 
=SUM(IF(FREQUENCY(IF($A$2:$A$12068=A8,MATCH("~"&$CK$2:$CK$12068,$CK$2:$CK$12068&"",0)),ROW($CK$2:$CK$12068)-ROW($CK$2)+1),1))

My question is whether it would be faster to calculate by using VBA? There are about 12,000 rows and even with an i7 quad-core processor on my new laptop, it looks like it would take about an hour to calculate.

Thanks,

Rob.

...confirmed with CONTROL+SHIFT+ENTER.

Hope this helps!
