Hi - I have a list of all certain census tracts in one column/workbook. On another workbook I have another list of census tracts, some duplicates, that may or may not exist on the first list. I am trying to identify the ones that are on both lists. VLOOKUP/MATCH don't seem to work. Maybe because the second list has duplicates? Please help! Thanks ![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
