Problema de programacion (SQL syntax)

[New_Race]

Bueno tengo este problema:

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'AND ID_MEMBER = 19' at line 1
Archivo: /home/Load.php(1571) : eval()'d code
Línea: 850

La línea que genera el problema es la siguiente:

$request = db_query("SELECT * FROM {$db_prefix}community_banned WHERE ID_COMMUNITY = " . $context['comunidad']['ID_COMMUNITY'] . " AND ID_MEMBER ='$ID_MEMBER' ", __FILE__, __LINE__);

y

db_query("DELETE FROM {$db_prefix}community_banned WHERE ID_COMMUNITY = " . $context['comunidad']['ID_COMMUNITY'] . " AND ID_MEMBER = '$ID_MEMBER' ", __FILE__, __LINE__);

No he podido solucionar el problema, necesito saber que esta mal..

Gracias por leer...
