On 360 why does it say -3 messeges and -1invite?

Question

When going to my homepage on 360 it reads that there is -3 (Negitive 3) messeges but there are no messeges in the mail box. I have -1 invites (negitive 1) and allowed to invite 100 more friends but it all ways comes up with an error messege when trying to invite others to join. Others have my invite but can not accept the invite.
