Only just started to attempt this.
I want to add an extra optional address field like the "Address 2" field. Am I correct in assuming that this field and the extra duplicate field are optional and could be left blank if not required by the user when completing registration? Is it only "Address" which is mandatory?
My initial approach was to add a field called "Address 3" below "Address 2" by copying the "Address 2" field code and pasting it directly below "Address 2" and then changing all references from 2 to 3 for the "Address 3" field.
However there is a lot of additional relevant code in this page so I'm sure this is not the correct way to achieve this.
Can you confirm that this approach is wrong and if so what is the correct method (is it by editing the form properly using the links in properties inspector)?
