inserire tabella relationship in una functions

[searedone]

così invece mi da':

Unknown column 'messages.usersuid' in 'on clause'

$query = mysql_query( "SELECT * FROM  
    messages INNER JOIN users ON (messages.usersuid=user.uid )  
    INNER JOIN relationship ON ( messages.relationshipid = relationship.id AND user_2 = '$uid' ) 
  OR messages.uid_fk IN 
      ( messages.relationshipid = relatioship.id AND user_1 = '$uid'  )  
    WHERE  
  messages.uid_fk='$uid' AND relationship.user_1 = 'S' AND relationship.user_2 = 'S' $morequery order by M.msg_id desc limit " .$this->perpage) or die(mysql_error()); 

Cavolo possibile che nessun riesce ad aiutarmi ....
