When I try to create a map, MapViewer says “There is no valid numeric data (within limits) in column __, or PID is invalid.” What causes this?
A. This error is usually an indication that the data file and boundary file are mismatched, or that the data are text instead of numbers. Check the Primary IDs for the base map in the Object Manager, then go to File | Worksheet and check the Primary IDs in the data file. If the Primary IDs do not match, then the map cannot be created.
