The trade and local fields that appear on the registration form can be customized and populated with your specific values. Use the Edit Trade Selections and the Edit Local Selections located in the Administration Area > settings tab to add values to these drop down form fields. You can change the trade and local field names to custom names in the Admin area > settings tab, Edit Website Settings link.
The local field selections require a name and a code for each entry. If you are using the field for local selections, enter the name of the local in the name field and then enter the unique local number into the code field. If you use the local field as a custom field with other data, make sure that the code value for each selection that you add has a unique value.
