Conditional Sum (2000 SP3)
I've done some searching and found a number of similar posts  but not one that matches what I'm looking for.
I've got over 900 rows x 10 columns of data. I want to sum values in one column based on matching information in another column. The matching data could be 1 or more (as many as 12). In the table below the first two columns is the data I have and I want to calculate the value in the third column. i.e. AA 100 + 200 = 300, AB 110 = 110, AC 150 + 95 + 100 = 345, AD 200 = 200. I've tried IFSUM, but that doesn't seem to work. Any other ideas? <img src=/S/please.gif border=0 alt=please width=31 height=23>
<table border=1><td>AA</td><td>100</td><td>AA</td><td>200</td><td>300</td></tr><td>AB</td><td>110</td><td>110</td></tr><td>AC</td><td>150</td></tr><td>AC</td><td>95</td></tr><td>AC</td><td>100</td><td>345</td></tr><td>AD</td><td>200</td><td>200</td></tr></table>

In C1:
=IF(COUNTIF(A$1:A1,A1)<>COUNTIF(A:A,A1), "",SUMIF(A:A,A1,B:)
Copy down the column...

Thanks  the conditional data is in column A but the numbers I need summing are in column E so I changed your formula to
=IF(COUNTIF(A$1:A1,A1)<>COUNTIF(A:A,A1), "",SUMIF(A:A,A1,E:E))
and copied down the column. However the results are mostly 0 (zero) I do get some results but they don't appear to be related to the values in E.
What am I missing?

Assume your range of data, "AA" started at A2
C2, enter the formula and copied down :
=IF(A2<>A3,SUMIF(A:A,A2,B:,"")

Re: Conditional Sum (2000 SP3)
Are the values truly numbers or are they text that just look like numbers? Remove any cell alignment, numbers align to right and text to the left...
Otherwise, could you post an example file with the problem?
