Have an user with Safari 3.x and his screen layout for this form is different then any I have ever seen and the "Proceed to Checkout" doesn't work, he has a button for "Preview". I have two different sections that one or the other will show based on the selection of a previous questions and he sees both no matter what he selects for the determining question. I'll make an educated guess, his browser version isn't supported.
If someone could give me a list of support version I will post it on the website with the form so users know.
Thanks, I knew it has to be on the website somewhere.
