Webform does't work :(

Hi,

I am using free Zoho for a non profit organization and i have a problem.
My web form doesn't work.
I tested it via my own website but when I fill it and send it, it does not go to the CRM system.
I don't understand why it doesn't work because i am following this tutorial:

Does someone know the problem?

Kind Regards

Joeri
