I think if I'm understanding this correctly(?), you want to add your PSN ID to your friend code list, but its giving you an error. You might want to try just adding it onto your profile or just PM your code to whoever is interested, I doubt the site staff will get round to fixing it anytime soon. Tbh I don't think anyone still active on these boards uses PSN IDs anymore, but its up to you.
