Cart66 + Gravity Forms = Equal Quantity and Form Field Submissions

I am using Cart66. They told me I could solve my problem by using Gravity Forms to accomplish the following:

We're selling event registrations and need to obtain attendee information for each registration at checkout.

Cart66 is set up fine. Gravity Forms is installed and the form is built.

The problem: If buyer updates the Cart66 quantity to 2, 3, 4, 5, etc. tickets in their cart, we need to be able to obtain the completed form fields on each registrant.

How do I begin? What needs to be done? Can it be done?

Okay, Carl, thanks for the really quick reply.

Just thought of a potential workaround, which I'll post here if anyone else finds themselves in the same boat.

Using: Wordpress, Pagelines Platform Theme, Cart66 and Gravity forms.

From registration page, i will create a list of links:

"Register Myself"
"Register Myself +1"
"Register Myself +2"
"Register Myself +3"
"Register Myself +4"

Each links to a page with a form with all necessary fields. that leads to multiple registrations with quantity populating Cart66.
