Is what i get, just changing the countif part to be column D, you were counting if your column a was in column a

=INDEX($A$1:$A$20, MATCH(0, COUNTIF($D$1:D1, $A$1:$A$20), 0))
Ahh okay I get it! Thank you!

Finally, is there a way to adapt it so that after I've dragged the formula down to say D10 and there are only 4 unique names, the other 5 formulas read "" instead of 0 or #N/A


Many thanks again!
