I get this error regarding the last product field, no matter which one it is. I cannot find any reference to this error anywhere here or on Google. This is a live form that seems to have worked and now doesn’t for this reason, and my client is dead in the water taking dinner reservations.
I’m using the latest version of WP and Gravity Forms.
I did, thanks. Turns out it was a caching issue with the Square for Gravity Forms plugin. Ended up simply putting the form on a new page and it worked.
