If cells values within a range match then return one value if not return another

Looking to create a formula:

If 2 cells within range A45:D45 are the same value then VLOOKUP(A45,$B3:$E45,20,FALSE) otherwise VLOOKUP(A45,$B3:$E45,3,FALSE). The problem I have is that the value could be anything.

Can anyone help.

You could try something like this:

=if(countif(A45:D45,A45)=2,VLOOKUP(A45,$B3:$E45,20,FALSE),VLOOKUP(A45,$B3:$E45,3,FALSE))

but that will only check for 2 cells being the same as A45, and it is not clear if that is what you want. If you are looking for any 2 cells in A45:D45 being the same, then you could try this:

=if(OR(countif(A45:D45,A45)=2,countif(B45:D45,B45)=2,countif(C45:D45,C45)=2),VLOOKUP(A45,$B3:$E45,20,FALSE),VLOOKUP(A45,$B3:$E45,3,FALSE))

If that isn't what you need, then please try to describe your requirements more clearly.

Hope this helps.
