Web forms are not working for my client

Web forms are not working for my client

Hi, I am trying to convince a customer to get ZohoCRM and Campaigns and we are now in the trial period and I am having a problem with web forms. I created one against potential clients and is not working.
You have the webform here:

It works well and it does reply with the confirmation page but it does not register in their crm.
Any ideas? thanks
