function getURLParam(strParamName){

      var strHref = window.location.href;
      if ( strHref.indexOf("?") > -1 )
    {
            var strQueryString = strHref.substr(strHref.indexOf("?")).toLowerCase();
            var aQueryString = strQueryString.split("&");
            for ( var iParam = 0; iParam < aQueryString.length; iParam++ ){
                      if (
                aQueryString[iParam].indexOf(strParamName.toLowerCase() + "=") > -1 ){
                        var aParam = aQueryString[iParam].split("=");
