Next it scans the database in feild 1, it finds a vehicle with = the same manufacturer it should make a secondary folder under that = manufacturer titled as the vehicle model. When finnished scanning the DB = it goes back to get the next line of the text file and so on. I've done = something wrong or I'm going about it the wrong way. I'm not up to = filling the list yet as I have to change the structure of the DB.
