messaggi privati php

[anselmojose]

Salve ragazzi,cercando nel web ho trovato questo script per creare messaggi privati all'interno del proprio sito,metto qui cosi da capire come è strutturata e se puo servire ad'altri.Posso dire che lo script funziona,nel mandare i messaggi,registrarli nella tabella e nelle sue varie parti.
Problema che non riesco a decifrare è che la pagina chiamata "read_message.php" non visualizza i messaggi in box ma solo mostra:
Title:
From:
Message:

[button]
E niente messaggi,qualcuno riesce a capire perche non si vedono i messaggi,vedendo lo scrip dell'ultima pagina sotto,appunto "read_messagge.php"?
Grazie

`message_contents` longtext NOT NULL,
`message_read` int(11) NOT NULL default '0',
PRIMARY KEY (`message_id`)
