Profile Builder Pro add multiple user roles on register form

[php]add_action( ‚wppb_register_success‘, ‚wppbc_add_role_after_completing_form‘, 20, 3 );
function wppbc_add_role_after_completing_form( $http_request, $form_name, $user_id ){
if ($form_name != ‚registrierung-fuer-unternehmen-und-organisationen‘) return;

$user = new WP_User($user_id);
$user->add_role(‚customer‘);
}[/php]

Afterwards when users complete the form you pointed out to me, they should also get the `customer` user role alongside the one they select.
