I have two columns. Column A displays the logon names being used

another sheet, but I'll simplify). What I want to appear on column
C is a list of all logons that are not being used. For instance:
COLUMNA:
Frank
Harry
George
COLUMNB
Frank
Harry
Jason
George
Steven
So what I want to appear in column c is:
Jason
Steven
I'd also like this to be dynamic, so as I pull logons and delete
them, the list updates as well. I've tried VLOOKUP and got sort of
an answer, but not quite the one. Any ideas?
This is fairly easy as long as you don't mind empty entries in your
resulting list. In C1 enter:
=IF(ISNA(VLOOKUP(B1;A$1:B$5;1;0));B1;"")
and fill it down the column.
This will display in column C your required Jason and Steven, but in
their original places as in column B, with empty cells where names
were matched. But it will update as you modify column A. If you
were fussed about the empty cells, you could sort the values, but you
would have to copy the values in C somewhere else first, using Paste
Special to freeze the result values, and then sort those values
instead. The sort would otherwise have no effect on the formulae in column C.
I trust this helps.
