Can someone help me with the formula here? I have used something like this before ={MAX(IF(…} but it doesn’t really fit what I’m doing now.

=MAX(IF(Sheet1!$A$a:$A$1500=Sheet3!D19,Sheet1!$G$1:$G$1500))

I need to identify that I have duplicates in column A, then look at column B and find the highest value for e.g. cat, then match this highest value with the highest in column C (as you can see “cat” has two 140 figures but in C one of them =56, thus I need “OK” next to it). I would be greatly obliged for your help.

```
Col A B C Formula?
cat 140 56 OK
cat 140 54 x
cat 87 41 x
cat 91 13 x
cat 100 11 x
dog 230 12 x
dog 230 55 OK
dog 230 45 x
mouse 111 12 x
mouse 123 43 x
mouse 145 55 OK
mouse 103 54 x
```

Try this in C2 and fill down.

```
=IF(AND(B2=AGGREGATE(14, 7, B:B/(A$1:A$13=A2), 1), C2=AGGREGATE(14, 7, C:C/((A$1:A$13=A2)*(B$1:B$13=AGGREGATE(14, 7, B:B/(A$1:A$13=A2), 1))), 1)), "OK", "x")
```
