AJAX/Javascript help

[iNod]

Hey,

I am trying to get this thing to work. But it doesn't.. Anyways enough n00bie stuff.. So.. Basically it used XMLHttpRequest to 'get' / 'post' a rate image id and a rating to rate.php. In the format of rate.php?r=votevalue&i=rateimageid.. I have the html side all done and I know it works.

Basically just
<a href="javascript:sendReq(1,rateimageidgoestherewithphp)" id="rating_1">Stuff</a>
...
...
... etc for 5 of them.. Each using the CSS rate image thingy.

The AJAX/Javascript code is this

function sendReq(vote,id_num) {
    
    /* Set up the request */
    var xmlhttp =  new XMLHttpRequest();
    xmlhttp.open('get', 'rate.php?r='+vote+'&i='+id_num);
    
    /* The callback function */
    xmlhttp.onreadystatechange = function() {
        if (xmlhttp.readyState == 4) {
            if (xmlhttp.status == 200)
                addRatingFeedback(xmlhttp.responseXML, target);
    }
}
xmlhttp.send(null);
}

function addRatingFeedback(responseXML, target) {
  var width = responseXML.getElementsByTagName('rating')[0].firstChild.data;
  document.getElementById('current_rating')style.width = width;
  document.getElementById('rating_1')href = '';
  document.getElementById('rating_2')href = '';
  document.getElementById('rating_3')href = '';
  document.getElementById('rating_4')href = '';
  document.getElementById('rating_5')href = '';
}

Myself not being that great at the old javascript just did what I know.

But for some reason.. When you click on it.. It is just not working.. The rate.php works because I tested that.. It is just this AJAX part..

Any help will be apprecited.
