I bet you wanted:

=MATCH(A1,C:C,0)

instead.

I think I'd use a slightly different formula:

=isnumber(match(a1,c:c,0))

If it's true, then there's a match. If false, then there's no match.

(It might be just a bit prettier than #n/a's and a bunch of numbers <vbg.)

Put your large (total ) list in column A and you list of bads in column C. In
B1 enter:

=MATCH(A1,C:C) and copy down. Then sort all three by column B. If column B
show #N/A then the entry is good. If column B shows a number the entry is
bad and should be removed.
