I have a sheet, with a list of products across the top and a list of stores down the side.

Against the rows and columns there are two possible data values, Correct and Incorrect.

What I am trying to do is to return a list of all the Store and Product combinations that cross reference with Incorrect.

My experience of array formulae is vitually zero, and I have a feeling that something clever with MATCH may well do the trick.

Can anybody help?

Many thanks,

Chris
