Hi Craig,
Many thanks for your prompt reply.
I am not handy at all in PHP, but I fell comfortable enough to adapt the code to the label of our form nevertheless, I read that the code “…requires use of an additional filter “rtec_attendee_list_fields” and I have no idea of what it is?
Moreover, as a volunteer I develop a web site for a non-profit association and at the moment they do not not consider to use the “pro” version.
Best regards,
André
