Integrate a Zoho Form with a Zoho CRM custom module

Integrate a Zoho Form with a Zoho CRM custom module

I have the free trial as of right now because I want to make sure it's going to work and give me what I need out of it.. 
I have created the custom module, and the zoho form. It integrated with no errors. When I fill out a test form it is not populating into my zoho crm.. Is this because I have a free trial and can't use the custom module? I have followed all the steps correctly. Form submits fine, but it is not populating.
