Macro to Compare Columns A & B and dispaly any duplicates in Columns C & D

Hi,

what I'm after is a macro to check the contents of Column 'A' against column 'B' and display any duplicates in Columns 'C' & 'D'.

N.B. The headings of Columns C & D are :-

C = Value Found in Column A

D = Value Found in Column B

Any duplicate entries logged in columns C & D should be listed in C2,C3,C4....C20 and D2,D3,D4......D20 etc (in effect creating two new lists)

Any assistance would be greatly appreciated


Regards
