Hi I having problem here how come the uid is undefined value on the actionscripts? the uname is able to be display but the uid is undefinded but I don’t know why it return undefinded value? uid is the id of the username like eg: 1,2,3

PHP Code:

$resultpostal=mysql_query("SELECT location.uname,location.uid FROM location,districts WHERE districts.districtno ='$postalno' AND
location.lat BETWEEN districts.startlat AND districts.endlat AND location.lng BETWEEN districts.startlng AND districts.endlng");$counterx=0;
while($row=mysql_fetch_array($resultpostal)){
foreach($row as $col_value){
$temp[$counterx]=$col_value;
$counterx++;
}
  $report.="uid"."=".$temp[0]."&";
  $report.="uname"."=".$temp[1]."&";   echo $report;

Anybody know?
