    I can't seem to make this work. I put an alert to vDmeString and tested it. It returns one row properly, however the next codes either gives me error messages methods not supported, null or not an object. Can you please help me fix the code below? The code is for ../xhrnet/personnelactions/pactions.htm. I cannot use jsreturn since it opens up a new frame list. I just need to get the code's description and put it into an input type text field.

        var vProd = authUser.prodline;
        var vDmeString = "http://lawsonprod/cgi-lawson/dme.exe?PROD=TRAINING&FILE=PCODES&INDEX=PCOSET1&KEY=";
        alert(vDmeString);
        var vDMEInfo = httpRequest(vDmeString);
        var tmpNode = vDMEInfo.getElementsByTagName('DESCRIPTION')[0];
        var uf_suppname = tmpNode.childNodes[0].firstChild.nodeValue;

    Thank you in advance.

      You need to look closer at the XML that is generated from your DME...there is not a node called description.
      The node you want to search for is RECORD.
      And you want to look at the 2nd column of the first record, something like this:

      var vDMEInfo = DMEobj.document.getElementsByTagName("RECORD");
      if (vDMEInfo.length == 0)
      {
      alert("No PCODES record found.");
      return true;
      }
      else
      {
      var vCols = vDMEInfo[0].getElementsByTagName("COL");
      var uf_suppname = vCols[1].firstChild.data;
      }

        as always thanks John. I am trouble shooting one line at a time, and var vDMEInfo = httpRequest(vDmeString); returns:typeof(vDMEInfo)==object and vDMEInfo.status==undefined. The string works when I paste it directly to IE but not through httpRequest. Any idea?

          var vDMEInfo = top.httpRequest(vDmeString);
          var vObjDMEXML = new top.DataStorage(vDMEInfo );
          var vRecords = vObjDMEXML.document.getElementsByTagName("RECORD");
