I'm looking to build a customer-facing form that will create info I can use in Zoho CRM.

Essentially: I want to be able to build a form that can take customer input after they know they want to sign up for our service, and then dump it into either a) their existing record or b) a new task that someone on my team can then follow up on.

I read  the examples over here, and I feel like I'm close, but can't quite understand how to do it. 

I was also unable to find the right support docs (other than the above) that would point me in the right direction.

Anyone?
