    seeing duplicates across two fields


      I have three fields supporter number, last name and postcode. What I am trying to do is to put a condition on the background colour of supporter number to say if the postcode and last name combination appears twice i want the supporter number to be coloured.

      I understand where to put this condition but I cannot work out what condition to use


      thanks in advance
