Associate a Zoho Form entry to a CRM contact

Associate a Zoho Form entry to a CRM contact

Hello, i am having trouble with having Zoho Form submissions associate with CRM contacts.  I currently have a custom module built in CRM called contracts.  I then have a contract form built in Zoho Forms that integrates with the fields in the Contract Module in CRM.  What i wish to do is have a way to have the contract Form show up as a related list of a specific contact.  So if "John Smith" submits a contract form, it will show up in "John Smith's" CRM profile as a related list.  

I used the "Zoho CRM" filed when buidling the Zoho Form and it worked perfectly!  However, the form needs to be a "public" form and the "Zoho CRM" field will not work in a public link, it only works as an internal link.

Any thoughts?
