The Forms Editor - Field Menu - Skip Blank option is used to move the field below the current field up.
If a field is marked Skip Blank, and if the field's value is empty/blank, the field below it is moved up. Skip Blank is most commonly used for Address fields only.
In order for Skip Blank to work, the field that is to be moved up must be one line below AND start in the same column as the field that it is to replace.
