We have a Purchase Order workbook where the first tab is a template. We copy that tab and enter data for various PO's as needed. One of our maintenance techs was producing PO's and now I am getting messages about names that exist in the Destination Worksheet and it ask me to rename them or keep them. Not sure what he did, but I need to eliminate them. I had done this once before, but do not remember what I did. Any assistance would be greatly appreciated.
