Ajax Simple Question - Please Help -- Very Frustrated

[quantass]

I am new to Ajax and decided to add it to my blog site but for the life of me i cant figure out why it keeps returning an error message in both IE and Firefox. The code is on Blogger.com but when i move it to another server it works fine. Here have a look I have put the code onto this test blogger site for you to try:


There are several alert boxes to help tell you where things are....And here is the code i am using on that page:

<script type='text/javascript'>
var c;
function o()
{
	if(c==undefined)
	{
		c=0;
		try
		{
                        alert("Starting Ajax call...");
			var vv = ax("http://z2.awardspace.us/1.js");
                        alert("Ajax call Returned - No Error - Parsing Data: ["+vv+"]");
			if (vv.length == 4)
			{
				c = parseInt(vv.substring(2,3));
				alert("Ajax Call Successful");
			}
			else
			{
				alert("Ajax Call Returned unexpected data content");
			}
		}
		catch(ee4)
		{
			alert("Ajax Call Failed - Catch:" +ee4);
		}
	}		
}


function ax(url)
{
    var xhr;
    try 
   {
        xhr = new ActiveXObject("Msxml2.XMLHTTP");
        alert("USE: IE Ajax API");
   }
   catch (ee1)
   {
        try 
       {
            xhr = new ActiveXObject("Microsoft.XMLHTTP");
            alert("USE: IE Ajax API"); 
       }
      catch (ee2)
      {
           try 
          {
              xhr = new XMLHttpRequest();
              alert("USE: Firefox/Safari Ajax API");
          }
          catch (ee3) 
         {
              xhr = false;
             alert("No Ajax capability");
         }
     }
  }

  if (xhr)
  {
      alert('CALLING: Ajax .open()')
      xhr.open('GET', url, false);
      alert('DONE: Ajax .open()');

      alert('CALLING: Ajax .send()')
      xhr.send(null);
      alert('DONE: Ajax .send()');

      return xhr.responseText;
  }
  else
  {
      return "";
  }  
}
</script>
