Constant HTML Errors

[kworsfold]

Hi, excellent article, thanks. However, there is one issue that I have found, that is the number of errors thrown up when debugging the HTML.
In the Function response(), in "get the xml stream" xmlResponse needs to be wrapped with if(this.responseXML != null){}

i.e.
// function to handle the response from the ESP
function response(){
var message;
var barwidth;
var xmlResponse;
var xmldoc;
var color = "#e8e8e8";

  // get the xml stream
  if(this.responseXML != null){


    xmlResponse = xmlHttp.responseXML;
    console.log(xmlResponse);

....
....
....
....
....

    }
  }   //  END If NULL

}
