Google Ecommerce Tracking with Gravity Forms PayPal Add-on

Hi,

I am trying to get the Google Ecommerce tracking set up with a site using Gravity Forms and the PayPal Add-on.

Here are docs on the Google Ecommerce tracking so you can see under the examples at the bottom, the info required once payment is complete: https://developers.google.com/analytics/devguides/collection/gajs/gaTrackingEcommerce

I am assuming I need to use the 'gform_paypal_fulfillment' hook (http://www.gravityhelp.com/documentation/page/Gform_paypal_fulfillment) to do this?

If so, in layman's terms, how do I then get then pass that data over to Google in the way it requires in Javascript?

Thanks for any help!

Nick
