    Ajax Simple Question - Please Help -- Very Frustrated

    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:

    Code:
    <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>

    ajax does not work cross domains... If it does, I do not know how it does, I have never been able to get it to work, I have heard it does not work across domains though. maybe I heard wrong, but like I said, never been able to get it to work myself...
