Specify User Field
Enter the Field Name.
Select the field Type (only available during initial creation):
Checkbox
Text Box
Drop-down
NOTE: Once you set the type (checkbox, text box, or drop-down) for a field, the FIELD TYPE CANNOT BE CHANGED, but you can edit the Field Name or the Drop-down values. But keep in mind that doing so will change the name and values for all your subscribers, including those who entered information using the older field name and values. Click here to see examples of why you should clear existing user defined fields before editing them.
If the field is a drop-down or a checkbox, enter up to eight (8) values for the drop-down or checkbox options.
Click the OK button to save your changes.
