Create books invoice from creator form

Create books invoice from creator form

I am having trouble creating a zoho books invoice from a creator form.  This is the code I have at the moment. 
Can anyone see what I am doing wrong?  
Note: i put MY ID to hide the actual number.


response = zoho.books.createRecord("invoices", "MY ID", { "contact_name" : input.Name, "company_name" : input.Company, "date" : input.Date_field, "phone" : input.Phone, "contact_persons" : {{ "email" : input.Email, "is_primary_contact" : "true" }} });

Any help would be appreciated!

Thank you!
