I would really appreciate it if someone could help?

I am trying to add a new field into phpautoresponder so I can collect the Name, Email & Company details of the subscriber.

I have added a new field within "phpMyAdmin" under "autorespondernk_subscribers" called "company" and is set up exactly the same as the field "name".

When I add a new name, email & company details via the index.php page I keep getting a message displaying "It appears that you have already subscribed to our mailing list..." which I know I haven't as the details do not exist in the database?

Any help or suggestions on getting this to work would be well appreciated
