All:

I'm trying to dynamically load a table using AJAX with RPG-CGIDEV2 as the 
back-end...and I'm getting a weird error that I don't really understand...

I have 3 fields on the web page that I'd like the user to fill out 
(tproject, lampcode, tooltype)...once all 3 have been filled out, I'd like 
to use AJAX to populate the table based on the data entered...2 of the 
fields are input boxes with appropriate onBlur events to call getToolRoute 
and the 3rd is a dropdown box with an onChange event to call 
getToolRoute...here's my AJAX...

function getXmlHttpRequestObject() {
  if (window.XMLHttpRequest) {
    return new XMLHttpRequest();
  } else if(window.ActiveXObject) {
    return new ActiveXObject("Microsoft.XMLHTTP");
  } else {
    alert("Your browser doesn't support AJAX!");
  }
}

var request = getXmlHttpRequestObject();

function getToolRoute() {
  if (document.getElementById('tproject').value != "" && 
document.getElementById('lampcode').value != "" && 
document.getElementById('tooltype').value != "") {
    if (request.readyState == 4 || request.readyState == 0) {
      var proj = escape(document.getElementById('tproject').value);
      var lamp = escape(document.getElementById('lampcode').value);
      var ttyp = escape(document.getElementById('tooltype').value);
      var type = escape(document.getElementById('type').value);
      for (var l = 1; l < 99; l++) {
        if ((type == 'T' && (l < 6 || l > 8 || l < 10)) ||
           (type == 'Y' && (l < 2))) {
          for (var s = 1; s <= 6; s++) {
            if (request) {
              request.open('GET', '/cgi-test/erqajxtrm?proj=' + proj + 
'&lamp=' + lamp + '&ttyp=' + ttyp + '&type=' + type + '&lvl=' + l + 
'&stp=' + s, true);
              request.onreadystatechange = handleRoute(l,s);
              request.send(null);
            }
          }
        }
      }
    }
    //request.open('GET', '/cgi-test/erqajxtrm?proj=' + proj + '&lamp=' + 
lamp + '&ttyp=' + ttyp + '&type=' + type, true);
    //request.onreadystatechange = handleRoute;
    //request.send(null);
  }
}

function handleRoute() {
  var x = handleRoute.arguments;
  var l = x[0];
  var s = x[1];
  if (request.readyState == 4) {
    var step = document.getElementById('lvl' + l + 'step' + s);
    step.innerHTML = '';
    //var msgs = document.getElementById('messages');
    var str = request.responseText.split("\n");
    if (str != "") {
      step.innerHTML = str;
    }
  } else {
    alert(request.statusText);
  }
}

and my html as follows:

/$routedetail
<tr id="level/%level%/" onMouseOver="this.bgColor='#cddfed';" onMouseOut=
"this.bgColor='#FFFFFF';">
<td align="center">/%level%/<input type="hidden" name="lvltype" id=
"lvltype" value="/%lvltype%/"></td>
<td align="center"><div id="lvl/%level%/step1">/%step1%/</div></td>
<td align="center"><div id="lvl/%level%/step2">/%step2%/</div></td>
<td align="center"><div id="lvl/%level%/step3">/%step3%/</div></td>
<td align="center"><div id="lvl/%level%/step4">/%step4%/</div></td>
<td align="center"><div id="lvl/%level%/step5">/%step5%/</div></td>
<td align="center"><div id="lvl/%level%/step6">/%step6%/</div></td>
</tr>

here's the error I'm getting:

uncaught exception: [Exception... "Component returned failure code: 
0x80040111 (NS_ERROR_NOT_AVAILABLE) [nsIXMLHttpRequest.statusText]" 
nsresult: "0x80040111 (NS_ERROR_NOT_AVAILABLE)"  location: "JS frame ::
