I need to get the unique values between 2 columns. For example, if A has
2,3,4,5 & 7 and B has 1,2,3,4,and 5, I need something to tell me that B
doesn't have 7. I expect to run through it again so that I see that A doesn't
have 1. I do not wish to enter in the data to search for, but rather have a
column comparison and kickout the differences (similar to a diff command on
Unix for those that know it).

Any help would be appreciated. The advanced filter doesn't do what I need
as it would give me all values.
Thanks,
Kelly
