Thanks again as always for all your past help! I come to you once again in hopes of resolving an Excel issue. I know it can be done… I just cannot figure it out. I have two spreadsheets. Spreadsheet 1 contains multiple PO#s in Col B (It does not provide me with the invoice #). Spreadsheet 2 contains invoice #s in col A and their corresponding PO # in Col B. What I am trying to figure out is how to use VLookup on Spreadsheet 1 to show me each occurrence of the invoice # that shares the same PO between the two spreadsheets. Maybe another formula would be better?
