One of our clients sells books on their website and was using a PayPal-generated Buy Now button to sell the book. However, they wanted to be able to sell multiple copies of the book so I added a form, using Gravity Forms with the PayPal Addon.

However, when I tested the form, it brought me to a page on Paypal with this error: “Some required information is missing or incomplete. Please correct your entries and try again.”

What the what?

After some trial and error (and minor freak-out), I figured out that my form is conflicting with the original PayPal “Buy Now” button which I hadn’t removed yet.


The solution: Remove the PayPal-generated “Buy Now” button 🙂
