NaN results for itemquery with Dbox

[william paul]

Hi:
   
  I am using Dbox and the example provided by Rich Greenwood, to map the results from a database query. I have modified the script so you can change the queryfile, qitem and qstring. The script works OK on 1 layer, but for others I get NaN. Before to map the results I test ( alert(qlayer, qitem, qstring)) to see if the queryfile, qitem and qstring are correct. Even though I have the core ct names for each one I still get NaN results
  What could be the problem?
   
  script from the database query results
  <script type="text/javascript" language="javascript">
  var qlayer = "anyQlayer";
  var qitem = "anyQitem";
  function map(qstring)
  {
  opener.itemQueryModified(qstring, qitem, qlayer);
  window.close();
  opener.focus();
  }
  </script>
   
   
  modified itemQuery script 
   ms.itemqueryoptions = "&mapext=shapes&savequery=true&";
 function itemQueryModified(qstring, qitem, qlayer)
 {
  //ms.setLayer(qlayer, true);
  var uri = ms.mapserver + '?map=' + ms.mapfile + "&layers=" + ms.getLayers("+") + "&mapsize=" + ms.width + "+" + ms.height;
  uri += ms.itemqueryoptions;
  uri += '&mode=itemquery'
  uri += '&qlayer=' + qlayer;
  uri += '&qitem=' + qitem;
  uri += '&qstring=' + qstring;
       var response = get_content(uri);
       var tokens = response.split(',');
  alert(qstring + qitem + qlayer + ", " + Number(tokens[1]), Number(tokens[2]), Number(tokens[3]), Number(tokens[4]));
       ms.setExtent(Number(tokens[1]), Number(tokens[2]), Number(tokens[3]), Number(tokens[4]));
       main.setImage(tokens[5]);
       ms.savedqueryfile=tokens[6];
  domouseclick('pan');
 }
