Mi aiutate ad aggiustare questo codice, non so perche' ma non trova dati gia' nella prima select. So che magari e' palloso per voi che queste cose sono note e stranote, ma io non so come fare

Primo ciclo

<?php $sql = "SELECT DISTINCT(LOGLKN) FROM VAM400.LOGMON00F order by loglkn";

$stmt = db2_exec($dbh, $sql, array('cursor' => DB2_SCROLLABLE));
while ($row = db2_fetch_array($stmt))
{ if (!$row=="")
{ $costumerLOGLKN = $row[12];
$_SESSION['costumerLOGLKN'] = $costumerLOGLKN;

Gia' qua se stampo $costumerLOGLKN non c'e' nessun valore, pero' io dopo di questo dovrei fare un qualcosa simile a questo

$sql = "SELECT * FROM VAM400.LOGMON00F where loglkn = '$_SESSION[customerLOGLKN]' ";

NON SO SE E' GIUSTA LA FORMATTAZIONE NELL'USO DELLA SESSION COME TEST

$stmt = db2_exec($dbh, $sql, array('cursor' => DB2_SCROLLABLE));

print '<table border=0 cellpadding9 cellspacing=0 bgcolor="#F7F7F7" bordercolor="#F7F7F7">';

while ($row = db2_fetch_array($stmt))
{
if (!$row=="") {
$costumerLOGDMS = $row[6];
$costumerLOGOMS = $row[7];
$costumerLOGTSM = $row[8];
$costumerLOGTRE = $row[11];
$costumerLOGLKN = $row[12];
$costumerLOGRMS = $row[10];
$costumerLOGSTJ = $row[13];
$costumerLOGDIF = $row[19];
$costumerLOGINO = $row[16];
$costumerLOGJOL = $row[15];
$costumerLOGLAL = $row[14];
?>

QUESTO TEST MI SERVE PER CAPIRE CHE LA VARIABILE NON HA VALORE

if ($costumerLOGLKN=="") {
