I did a Quick Setup, but it shows the DDF as 'No Database Assigned'?
Using the Quick Setup function in the Database Definitions window creates the settings for a DDF from the selected database file. But it does not set that file as being the current database file assigned to the DDF.
Use the Select Database button on the Database Definitions window to point to the current database file to be used by the DDF. AutoPrice will associate the Current DDF to the selected database file until the Select Database command is used again, or until that file is deleted.
Note that the Select Database command is also located from the menu command AutoPrice > Setup > Select Database, or from the flyout menu at the upper-left corner of the AutoPrice floating palette.
