Hi - I would like to find duplicates of names that sit within two columns, that I have in Libre Office Math (v3.5 I believe). I have a list of names that sit in column a, and a list that sits in column b, but do not necessarily sit across from one another in a row. I need to identify where there are duplicates (and highlight them some how) so I can see which names appear in both columns.
Many thanks for your help!
