MS Office Forum / Excel / Worksheet Functions / October 2006COUNTIF with multiple conditions?
(Note: I also posted this on Excel / General questions. I hope I'm not violating a rule by double-posting.) I've got a table A2:Z100, with X's in some of the cells. A row may have one or multiple Xs. I'm trying to find the number of rows which are "pureplays", which is defined as a row with only one X. For each column, I'd like to count the number of pureplays for that column only, and put that value in the top row. So, for example, C1 would count the number rows that have contain one X only and that X is in column C. (I can't figure out how to do it with COUNTIF. A formula COUNTIF(C2:C100,"X") will count the number of Xs in column C, but it's not limited to the rows containing only one X.) Any ideas?? Thanks. This looks like a sumproduct question to me, but I'm not sure it can handle 26 different conditions. =SUMPRODUCT(--(A1:A100="X"),--(B1:B100="X"),--(C1:C100="X")) would give you the number of rows that only have X in them in columns A-C. > (Note: I also posted this on Excel / General questions.

Just do: =IF(COUNTIF([range],"X")=1,"only one X","other") Dave  SignatureBrevity is the soul of wit. > This looks like a sumproduct question to me, but I'm not sure it can handle > 26 different conditions.

Hi Eric You could do it with two additional columns AA and AB in AA2 =IF(COUNTIF(A2:Z2,"X")=1,1,"") in AB2 =IF(AA2=1,CHAR(MATCH("x",A2:Z2)+64),"") Copy AA2:AB2 through AA3;AA100 You will now have a column of data where the column letter containing only a single X in the row is shown.

Try this for column A: =SUMPRODUCT( ( A$2:A$100 = "x" ) * ( COUNTIF( OFFSET( $A$2:$Z$2, ROW( A$2:A$100 ) - 2, 0 ), "x" ) = 1 ) ) Drag-fill as needed. SignatureRegards, Luc.

SignatureRegards Roger Govier > Try this for column A: > [quoted text clipped - 27 lines] >> >> Thanks. Thanks. Clever. I didn't know that a logical value works as a 0/1 in multiplication. Although I'm new to SUMPRODUCT, I think that your formula needs a little adjustment. Either replace the asterisk with a comma (to separate the two arguments of SUMPRODUCT), or use simply SUM instead. Does that seem right to you? Thanks for your help. > Try this for column A: > [quoted text clipped - 21 lines] > > > > Thanks. No. But don't take my word for it, try and play with your ideas/solutions... There is more than one way to do this, using SUMPRODUCT, SUM, COUNT, etc. SignatureRegards, Luc. "Festina Lente" > Thanks.
