Sorry, I accidentally sent my message to James instead of the mailing list. Let me recap what we discussed off-list.

As I see it, the formula is looking at the values in column A and checking which of those values matches the condition in A7. Then you want the formula to count the cells in column Q where the match occurred. But it does not matter which cells you count, because you only count the matches in column A (which has nothing to do with column Q or R). It seems difficult to explain what I mean, let me try an illustration: There are 5 apples (3 red and 2 green) and 5 pears. Each apple has a number from 1 to 5 and each pear has a number from 1 to 5. Count the pears that have numbers that corrospond to red apples. The answer would be 3. But you could just have counted how many apples are red. Maybe you just want something like this: =IF(countif(Q$3:Q7,A7) = countif(R$3:R7,A7),SUMIF(A$3: A7,A7,R$3:R7)-SUMIF(A$3:A7,A7,Q$3:Q7),"Error 4") That said, it is difficult to visualise the goal of the formula. I suspect I don't quite know what you want. If you could upload a sample document (with sensitive data removed) it might be easier to understand.
