Identifying unique values among duplicates
If sheet2 cols A and C match the value in sheet1 cols H and I, I want to
return the number of unique values in sheet 1 column A. Can anyone provide a formula for accomplishing this: The following example should yield a result of 2 for the Arenas/Bibby combination because there are two rows in sheet1 where Arenas is in colH and Bibby in colI, AND the date in colA is unique (10/29/08 and 10/30/08): sheet2 colA colC Arenas Bibby sheet1 colA colH colI 10/29/08 Butler Simmons 10/29/08 Arenas Bibby 10/29/08 Thomas Brown 10/30/08 Arenas Bibby 10/30/08 Stevens Hale 10/30/08 Arenas Bibby 10/30/08 Stevens Simmons 10/31/08 Arenas Simmons Thanks, Bob |

Try this array formula** entered on Sheet1:
=COUNT(1/FREQUENCY(IF((H2:H9=Sheet2!A1)*(I2:I9=Sheet2!C1),A 2:A9),A2:A9)) ** array formulas need to be entered using the key combination of CTRL,SHIFT,ENTER (not just ENTER) -- Biff Microsoft Excel MVP "bob" wrote in message ...

Biff,
This works very well and yields the correct answer when I set up the formula in sheet1, but how would I set up the formula in sheet2 (which is where I really want it)? Bob "T.
