Help! Sending Request, yet no readystatechange..

[Toarluath]

So I have a problem that I can't seem to fix, no matter what I do.
The code below SHOULD create a 'slideObj' object and then use it to get some information from a php file called queryslides.php.

However, the code seems to only get to sending the request; it never RECIEVES any data back.
The function outlined in "this.request.onreadystatechange = this.infoReturn;" which is infoReturn() never gets called up. Everything before it works great, but it stops after the onreadystatechange part.

I have my code below, with comments inserted for ease of reading.

function slideObj() {
this.request = null;         //get a request object
   try {
     this.request = new XMLHttpRequest();
   } catch (trymicrosoft) {
     try {
       this.request = new ActiveXObject("Msxml2.XMLHTTP");
     } catch (othermicrosoft) {
       try {
         this.request = new ActiveXObject("Microsoft.XMLHTTP");
       } catch (failed) {
         this.request = null;
       }
     }
   }
 
    if (this.request === null) {
     alert("Error creating request object!");  
}
 
 
 
   function sendGetServer() {
       this.request.open("GET", "queryslides.php", true); 
 
//queryslides.php is a php file with only one active line
//<?php
//echo "1|r|d~3|s|f";
//?>
 
     this.request.onreadystatechange = this.infoReturn;
     this.request.send(null);
     alert('Message Requested');  
    }
 
 
//HERE IS THE PROBLEM *****
//Every 'alert' is activated, except for those in the two functions below 
 
   function infoReturn() {
     if (this.request.readyState == 4) {
       /* Get the response from the server */
       var info = this.request.responseText;
    alert('Info recieved');
       /* Format Data */
       this.goOn(info);
      }
 
   }
 
 
//The next function works by itself, so this isn't really a problem
//
// Except for the alert line, you can just pretend the goOn() doesn't do anything.
 
        function goOn(inf) {
 
            alert('working?');
 
        }
 
this.goOn = goOn;
this.infoReturn = infoReturn;
this.sendGetServer = sendGetServer;
}
 
var hey = new slideObj();
hey.sendGetServer();
alert('end');

What can I do?
I have a link to the page here: http://hiroshifukada.no-ip.biz/sense/TEST.html~ (Note: The linked file is not EXACTLY the same as the example I gave. I'll update the file to what I show here as soon as I can.)

Sorry about this, I accidentally set the prefix to 'Resolved' even though I didn't mean too.
Can we delete this 'accidentally resolved' thread?
