Hi, 

New to Zoho and trying to find my way around...

Have a main form with client details - which contains a subform for different contact persons within that company.

In the second main form -  to create projects - I would like to be able to use a dropdown to select a contact person for that job, dependent on the client that has been selected.

This is what I've been playing around with so far, from looking around other forum answers, but I'm not sure if I'm missing something obvious or just going around it in completely the wrong way?

if(Client_Details[ID == input.Client].count() > 0)

{

temp = Client_Details[ID == input.Client];

        input.Address = temp.Address;

input.Currency = temp.Currency;

clear Contact;

for each  Contact_Person in Client_Details[ID = input.Client]

{

for each item in Contact_Person

{

input.Contact:ui.add(Contact_Person.Name.tolong());

}

}

}
