Count Unique Numbers if Names Match
I have a summary sheet and a list of names, in ColumnC, on this sheet. Im
trying to figure out a way to find a match in names in ColumnC of Sheet2, and then count unique numbers, in Column G, for these names. I was experimenting with this: =SUMPRODUCT((Sheet2!$C$2:$C$1000=C57)/(COUNTIF(Sheet2!$G$2:$G$1000,Sheet2!$G$2:$G$1000&" "))) This comes pretty close, but the numbers are off a bit. Any idea how to do this? Thanks, Ryan--- -- RyGuy |

I can't see anything wrong with the formula. In what way are the numbers 'off a bit'? Mike "ryguy7272" wrote: I have a summary sheet and a list of names, in ColumnC, on this sheet.

Count Unique Numbers if Names Match
Hi,
This 'may' be a slight improvement to eliminate blanks being counted =SUMPRODUCT((Products!C2:C1000=C57)*(Products!G2:G 1000<"")/COUNTIF(Products!G2:G1000,Products!G2:G1000&"")) Mike "Mike H" wrote: Hi, I can't see anything wrong with the formula.

Count Unique Numbers if Names Match
Well, the results are just wrong. For one guy, named Ryan, not me though,
the result should be 32 unique numbers on Sheet2. The formula is giving me a result of 30. I know this because I used the Advanced Filter to copy/paste uniques to a new sheet. Also, some of the results are fractions, and I can see this when I increase the decimalization. I should never have 12.33333 unique numbers; I should always have a whole number. I guess this is a result of the division operator. As I mentioned before, it is close, but not right. Any other thoughts?

Hi,
I don't doubt for a moment you are getting the results you say but I'm baffled. If we consider how the formula works with a slightly modified version for clarity =SUMPRODUCT(--(Products!$C$2:$C$10=C57)/(COUNTIF(Products!$G$2:$G$10,Products!$G$2:$G$10&" "))) if c2 - c10 are all the same as c57 then this bit returns an array of 1s this bit (--(Products!$C$2:$C$10=C57) returns SUMPRODUCT({1;1;1;1;1;1;1;1;1} if in the next column we have 5 number 1 and 4 number 2, this bit COUNTIF(Products!$G$2:$G$10,Products!$G$2:$G$10&"" ) returns {5;5;5;5;5;4;4;4;4}) if we then product those 2 arrays we get ..2;.2;.2;.2;.2;,25;.25;.25;.25 if we then sum this array we get 2 for the 2 unique values so again i'm baffled how this returns a decimal and hope someone can rescue us (me) Mike "ryguy7272" wrote: Well, the results are just wrong.

Count Unique Numbers if Names Match
find a match in names in ColumnC of Sheet2,
and then count unique numbers Try this array formula** : =COUNT(1/FREQUENCY(IF(Sheet2!$C$2:$C$1000=C57,Sheet2!$G$2:$ G$1000),Sheet2!$G$2:$G$1000)) ** array formulas need to be entered using the key combination of CTRL,SHIFT,ENTER (not just ENTER). Hold down both the CTRL key and the SHIFT key then hit ENTER. The problem with this formula: =SUMPRODUCT((Sheet2!$C$2:$C$1000=C57)/(COUNTIF(Sheet2!$G$2:$G$1000,Sheet2!$G$2:$G$1000&" "))) If the same number is associated with more than 1 name then you get incorrect results.

Tom...40
Tracy ...40 Thanks for pointing that out, it's about the only thing I never tried to make the formula error out but as soon as you have the reason for the decimals is obvious. Mike "T.

Count Unique Numbers if Names Match
Hi,
You can also try this. This is a non-array formula solution 1. Assume that in sheet 2, you have data in E5:F9 as follows: Name Number Ashish 12 Mahesh 23 Ashish 34 Mahesh 12 Rajesh 12 2. In B3:D3, enter data as follows Name, Occurrence, Count unique 3. In B4:B6, enter Ashish, Mahesh, Rajesh 4. In C4, enter =COUNTIF(Sheet2!$G$6:$G$10,Sheet2!G$6) and copy down till C6 5. In cell D4, enter =DCOUNT(Sheet2!$C$5:$G$10,Sheet2!G$5,Sheet1!$B$3:C 4)-SUM($D$3:$D3) and copy down till D6 Please note that this formula will work only when the col. G entries in sheet 1 are all numbers. Hope this helps. -- Regards, Ashish Mathur Microsoft Excel MVP www.ashishmathur.com "ryguy7272" wrote in message ...

Hi Biff, Mike,
I have same kind of problem. I need to get unique values in a column using sumproduct. I have lets say column named ranges as BU and Subscriber. Both are text. I tried =SUMPRODUCT(1/COUNTIF(Supervisor,Supervisor), -- (BU="NA")) which gives me result in fractions and =COUNT(1/FREQUENCY(IF(BU="NA",Supervisor),Supervisor)) which gives result as 0. Bothe are incorrect Pls help Regds Manish On Friday, February 06, 2009 2:43 PM ryguy727 wrote: I have a summary sheet and a list of names, in ColumnC, on this sheet.
