Count if function with 2 criteria

**santaigob09** · 02-13-2012, 11:13 AM

Hello, I wanted to know if its possible to use the "count if function" (or any other function) with more than one criteria.
When is use the [COUNTIF($A$2:$A2,A2)] formula in column C, I'm able to obtain the number of times ID (column A)is present in my data.
I would like to know if there is a way to use 2 criterias (ID and LACT) and obtain something like I have in column D. Were the formula would account for both ID and LACT. I'm working with really large datasets and it would be really helpful to be able to sort my data easily.

Thanks

ID LACT COUNT ID ID and LACT as criteria
974 4 1 1
974 4 2 1
974 4 3 1
974 4 4 1
986 5 1 1
986 5 2 1
986 5 3 1
986 5 4 1
986 5 5 1
986 5 6 1
986 5 7 1
986 5 8 1
986 5 10 1
986 6 14 2
986 6 15 2
989 4 1 1
989 4 2 1
989 4 3 1
989 5 4 2
989 5 5 2
989 5 6 2
989 5 7 2
989 5 8 2
989 5 9 2
989 5 11 2

Hi

Try this.

=SUMPRODUCT(($A$1:$A$20=A1)*($B$1:$B$20=B1))

Hope to helps you.

Thank you for your help Fotis. I will play a little with this formula and let you know.

OK! I'll wait

With Excel 2007, you can use COUNTIFS too...

=COUNTIFS($A$2:$A2,$A2,$B$2:$B2,$B2)

Hello guys,

Thank you very much for your help. I have been trying with both formulas and none of them seem to be working as I expected:
Probably I didn't make a good job explaining what I wanted. But what I would like to get with the formula is something like I present below (What I would like). Basically I would like to know if there is a formula that can account for both ID and LACT and give me a value. For example: ID 974 has LACT values of 4 for all the observations, therefore I would like to get all 1 (LACT level for that ID didn't change). For ID 986, notice that it has 2 levels of LACT 5 and 6. What I would like for this particular case is that the formula label the all the combinations of ID 986 and LACT 5 as 1 and all the combinations of ID 986 and LACT 6 as 2. Similarly for ID 989 LACT 4 get 1 and for the combination of ID 989 LACT 2 get 2. Hope this clarifies what I'm looking for.

Thanks again for your help

Here is a better picture for clarificationCapture1.JPG

If everything is grouped as per your attachment, then assuming data starts in A2 and B2, try in new column:

=IF(A2<>A1,1,IF(B2=B1,C1,C1+1))

To best describe or illustrate your problem you would be better off attaching a dummy workbook, the workbook should contain the same structure and some dummy data of the same type as the type you have in your real workbook - so, if a cell contains numbers & letters in this format abc-123 then that should be reflected in the dummy workbook. Don't upload a picture when you have a workbook question. None of us is inclined to recreate your data. Upload the workbook and manually add an 'after' situation so that we can see what you expect. In addition clearly explain how you get the results..
