xmlhttprequest http.status unknown

[rpjd]

I am having a problem getting the http.status of an xmlhttprequest. The request readystate has come back as readystate 4, but then it stops without confirming the http.status. Any help appreciated.

<script type="text/javascript" >
var postring = "?";
function string()
    {
        var first = document.numbers.first.value;
        var second = document.numbers.second.value;
        var third = document.numbers.third.value;
        postring += "first=" + first + "&second=" + second + "&third=" + third;
        alert(postring);
        insert();
    }
function insert(url)
    {
    var url="http://localhost/Project/Hi.php";
        var http;
 
        if (window.XMLHttpRequest) 
        { // Mozilla, Safari, ...
            http = new XMLHttpRequest();
            if (http.overrideMimeType) 
            {
                http.overrideMimeType('text/xml');
                // See note below about this line
            }
        } 
        else if (window.ActiveXObject) 
        { // IE
            try {
                http = new ActiveXObject("Msxml2.XMLHTTP");
                } 
                catch (e)
                {
                 try {
                      http = new ActiveXObject("Microsoft.XMLHTTP");
                      } 
                 catch (e) {}
                }
        }
        if (!http) 
        {
            alert('Giving up :( Cannot create an XMLHTTP instance');
            return false;
        }
        alert('ok');
        http.onreadystatechange = function()
        {
        if (!http.readyState)  
            {
               alert('There was a problem with the request.');
            }
        else
        alert(http.readyState);
        if (http.readystate == 4)
            {
            alert(http.Status);
            if (http.Status ==  200)
                {
                response = http.responseText;
                alert(response);
                document.numbers.first.value = "";
                document.numbers.second.value = "";
                document.numbers.third.value = "";
                }
            }
        }
        http.open('POST', url+postring, true);
        http.send('');
    }
</script>

Heya, rpjd.

Is it http.Status, or http.status?
