data validation over 2 columns? [Solved]

data validation over 2 columns?

Hi all,
 
I'm trying to setup a spreadsheet that will prevent a user from entering duplicate data over two columns.
So, :
 
A                     B
Smith             John
Smith             Jane
Smith             John
 
I would like excel to prevent the third entry above.
Is this possible?
 
TIA,
 
Jim
