I am attaching a sample Excel file. On Sheet 1 column A are phone numbers. on Sheet 2 in Column A is a list of the phone numbers and in Column B is updated phone. In column B (Sheet 1), I want write a Vlookup to Column A (Sheet 1) and then find a Match in Column A (Sheet 2) and bring back the Updated Phone Number Column B (Sheet 2) into Column B (Sheet 1). I am working on a much larger Excel file the sample file, but it's not working correctly (only some of the numbers are populating). So I think I might be doing the Vlookup incorrectly. Any info is greatly appreciated, thank you. Book1.xlsx
