PHP to actionscript is Undefined!

Hi why do my actionscripts keep displaying undefined when I done a trace?
Basically this is my php code it should pass the value uid and uname to my actionscript however it does not show the uid and uname that it suppose to show after I trace why is it like that is something wrong with my php or actionscript plss help thx!

PHP<?php

$sqlconnect=mysql_connect(“localhost”,“hyperian_track”,“gsmtrack”);
if(!$sqlconnect)
die(mysql_error());
mysql_select_db(“hyperian_track”, $sqlconnect);

if($_GET[‘postal’]))
$postalcode=substr($_GET[‘postal’],0,2); //will return from 0 position 2 characters
$resultpostal=mysql_query(“SELECT location.uname,location.uid FROM location,districts WHERE districts.districtno =’”.$postalcode."'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 $report;
mysql_close($con);
}
?>

Then my actionscripts code is as follow:

Actionscripts

function getpostal(){

var postalIn:LoadVars = new LoadVars();
postalIn.onLoad = function(success) {

if (success){
trace(this.uname);

}

}
postalOut.postal=postal.text;
var postalOut:LoadVars = new LoadVars();
postalOut.sendAndLoad(passingurl, postalIn, “GET”);
}
By right it should at least display the uname but it just show undefined iszit the way I return the value from php to actionscript is wrong?
