Oh! thank you.
I changed the form action URL and it appears to work. It takes me to a sign up form that says there are errors on the page and asks for imputing separate fields of first and last name. Would I be correct in understanding that this is due a setting in MailChimp for including all of the fields? I have been testing out different styles of forms and some ask for separate first name/ last name? Style2 only asks for an email address.
