This option allows the user to establish up to 10 additional data fields that relate to county and zip code.  There are up to 3 extra user data fields (10 in Advanced & RM/Pro) that can be defined in the user in the County and Zip Code databases.  This option allows the user to enter the name/description of these "extra" data fields.  Care must be taken when establishing these as changing the fields later requires the data in the County and Zip code databases to be reinitialized for this data.  For more information see the County or Zip code data maintenance section.
