$sql="SELECT * FROM ipms_user a, ipms_ref_area b WHERE a.user_type = 'm' AND a.seating_group = 'R' AND a.area_id = b.area_id";
$res = mysql_query($sql) or die(mysql_error());
?>

<form name="form1" method="post" action="<?php echo $_SERVER['PHP_SELF'].'?module=aum&op=senaraiSoalanMP&ptrid='.$ptrid.''?>">

while ($row = mysql_fetch_array ($res))
{

$i++;

for($i=0; $i<count($ar_dato);$i++) {
