you need to edit include/help.php too

remove the fields you dont want to check for

    $fillerror = (empty($contact["firstname"]) || empty($contact["lastname"]) || empty($contact["b_address"]) || empty($contact["b_city"]) || empty($contact["b_country"]) || empty($contact["b_zipcode"]) || empty($contact["phone"]) || empty($contact["email"]) || empty($contact["subject"]) || empty($contact["body"]));
