Actionscript error: HTTP request error

Question

Why do I get this kind of actionscript error? Everytime my page loads up this error immediately shows up:
[RPC Fault faultString="HTTP request error" faultCode="Server.Error.Request" faultDetail="Error: [IOErrorEvent type="ioError" bubbles=false cancelable=false eventPhase=2 text="Error #2032: Stream Error. URL: http://localhost/trytryjfsjfs-debug/total.php" errorID=2032]. URL: http://localhost/trytryjfsjfs-debug/total.php"]

I checked the said URL and this is my code of total.php:
<?php
$projName = mysql_real_escape_string($_POST["projNameTI"]);
$query = "SELECT itemno, divno,descs,qty,unit,unitcost,qty*unitcost as subtotal, SUM(qty*unitcost) as total,psid,project_id FROM projectspecs
Where project_id = (SELECT project_id FROM project where name='$projName')";
$result = mysql_query($query) or die ("Query failed: ".mysql_error() ."Actual query: ". $query);
?>
It seems that this code works perfectly
Can someone please help me about this problem, just an explanation how to get this well.
Hoping for a response.

http://localhost/trytryjfsjfs-debug/total.php?projNameTI=3       (what ever you have as the id in the db.)
try to use this URL in your browser and see what you are getting.
