Ok, I thought I had this pegged but then I actually tried to use the page I've been building. :/ I'm working on having a short form at the bottom of every post, and am populating a hidden field with the post title to know which form was submitted.
I just now found the forum posts saying that this isn't possible. We could deal with duplicate entries, but on submission every field changes to the success message and AJAX validation is out of the question.
Any updates on this? Otherwise I guess I'll just have to change things so you're taken to another page to fill out the form.
Thanks!
