    You have spelling mistakes/colons instead of semi-colons... just clerical errors...

    This works...
    <html>
<body>

<script type="text/javascript">
function ajaxFunction()
  {
  var xmlHttp;
  try
    {
    // Firefox, Opera 8.0+, Safari
    xmlHttp=new XMLHttpRequest();
    }
  catch (e)
    {
    // Internet Explorer
    try
      {
      xmlHttp=new ActiveXObject("Msxml2.XMLHTTP");
      }
    catch (e)
      {
      try
        {
        xmlHttp=new ActiveXObject("Microsoft.XMLHTTP");
        }
      catch (e)
        {
        alert("Your browser does not support AJAX!");
        return false;
        }
      }
    }
    xmlHttp.onreadystatechange=function()
      {
      if(xmlHttp.readyState==4)
        {
        document.myForm.time.value=xmlHttp.responseText;
        }
      }
    xmlHttp.open("GET","ajax2.html",true);
    xmlHttp.send(null);
  }
</script>

<form name="myForm">
Name: <input type="text"
onkeyup="ajaxFunction();" name="username" />
Time: <input type="text" name="time" />
</form>

</body>
</html>

    1. Everywhere you have responce please replace it with response. Responce is not a word in ASP.

    2. Don't use document.myForm.time.value=xmlHttp.responceText; instead use
    document.getElementByName('time').value = xmlHttp.responseText

    Give that a try and come back to me

    Stop being pedantic... he already fixed his spelling mistakes and he's got the element value changing.

    Instead of the asp page that you have just send something like one character instead. One step at a time.

    So your time.asp will just contain this...
    A
