I think Zoho is great but I am not a coder 

I am trying to fetch an email record for a customer from one form into another.

I have Two forms

Form 1 “New_Contact”  Field Names are “Company_Name” and “Email_Cust

Form 2 “Order_Details” Field Names are “Customer” and “Email”

When I do look up of customer in Order_Details  in field “Customer” I want it to fetch “Email_Cust and put it in “Email”

Can anyone help me with the code.
