I have a list of 408 people who need review for an award. However, of the
408 I have already entered an award for 193 people.

I have an Excel spreadheet which lists in column A the larger list and in
column B the people who already have the award. I am trying to filter the
unique records from column A by comparing column B. However, I do not seem
to be able to get the results I need; in fact I am getting no results.

Can anyone help? I was able to do this very function before with little
difficulty but seem to have a problem now.

Sorry if this is a bit vague. I can provide more information if needed.

Thanks.
