thank you for your response.

i must clarify, the value in each cell are words not numbers (eg: smith, joe
1253).

the columns are identical in terms of spelling, grammar, spacing, etc.

i just need to identify new names added to this list. the names would show
up in column A but be absent from column B.

should i change the ISNUMBER command?

I have two columns range(A1:B1443). All I need to do is take the value of
B1
and compare it to every item in column A. If this value appears in column
A
at all, I would like C1 to return a value of 1, and if it does not appear
I
would like C1 to return a value of 0.
