I don't understand how to implement this formula:
Code:
IFERROR(INDEX($C$23:$C$265, MATCH(0, COUNTIF(N$23:$N23, $C$23:$C$265), 0),1),"")

I need to remove the duplicates in list C23:C265 and place the new entries in N23:N52


I've tried putting it in cell n23 and copying down but it doesn't produce anything. Thanks for any help!
 

Excel Facts

Test for Multiple Conditions in IF?
Use AND(test, test, test, test) or OR(test, test, test, ...) as the logical_test argument of IF.
