SEeing if a number in one column is in another column
I am working in Excel 2003. I have two columns of numbers (ID numbers for
employees of 6 digits each). If a number appears in column A (there are no
duplicates of this number in column A), the number must NOT appear in column
B. Is there any way, besides VBA, to check if a number appearing in column
A is also listed in Column B?
Thanks,
Ricki
