I would like to use my Gravity Form plugin, with Cart66. I have used it for another project and works great. This project is a little different though.
We are creating a donation website, and want to let Donors select their donation amount. I see this can be done using the "User Defined Field" in both Cart66 and Gravity Forms. How do i set it up, so whatever amount is placed in the Donation field on the Form, is passed on to the shopping cart ? At the moment, nothing is being passed to the shopping cart.
