Howdy,
I haven’t verified these settings, but the first name field and the e-mail field need only the actual field name, e.g.
instead of
Email field: <input type="text" name="fields_email">
First name field:
<input type="text" name="fields_fname">
try:
email field: fields_email
first name field: fields_fname
Cheers!
Excellent, that worked. I also had to use my unique special ID (not the one you used in the other example). Thank you!
