how to pass the record id from one form to another?

how to pass the record id from one form to another?

I have the following "views" in zoho:
 
CLIENTS
- (automatic ID ? does not appear anywhere)
- Name
- Email
- Birth date
 
then I have another table:
 
QUESTIONS
- Client ID (this is a lookup from the 'Clients' table)
- What is your favorite color? (radio: black, white, blue)
- What is your car's brand? (picklist: Toyota, Ferrari, Volvo)
 
 
 
then I have the form for "Clients". when I click on SUBMIT, I want to pass the client's id to the second form. How do I do that? Does it matter if the form is stateless?
