bright order status

hi i was looking at the examples to get order statuses from bright custom order statuses plugin into the custom template with this code
add_filter( ‘viwec_accept_email_type’, function ($email_types) {
$email_types[] = ’email_id_1′;
$email_types[] = ’email_id_2′;
return $email_types;
}, 9999 );

but somehow cannot get this to work. any help with this would be appreciated
