Chain-linking fields from several forms

Chain-linking fields from several forms

Hi all,

I have a simple application for a basketball club membership on Zoho Creator.

I have created three forms:

1. Person (containing individuals' details, e.g. First Name, Surname, Date of Birth, Street Address, Suburb).  Suburb is a lookup from the Suburb form.
2. Suburb (containing Suburb Name, Post Code and State).  State is a lookup from the State form.
3. State (containing only State).

I would like to display on the Person form the Suburb Name (which works) PLUS a "calculated" field which, once Suburb is picked up, it automatically displays the Post Code from the Suburb form and the State from the State form.  Something like:

Suburb.Suburb + Suburb.PostCode + State.State

I can't really find whether such a construct is possible and, if possible, how to script it.  Could someone assist, please?

Thank you in advance.
