Service Catalog: spit out variable values

in an email notification script for example

<mail_script>

var item = new GlideRecord("sc_req_item");

  item.addQuery("sys_id", 'f5a6ff1b37a993c08ca1138943990ee6');

  item.query();

  while(item.next()) {

   

      gs.print(item.number + ":  " + item.cat_item.getDisplayValue() + " \n");

      gs.print("    Options:\n");

      var keys = new Array();

      var set = new GlideappVariablePoolQuestionSet(); 

      set.setRequestID(item.sys_id);

      set.load();

      var vs = set.getFlatQuestions();

      for (var i=0; i < vs.size(); i++) {

        var sLabel=vs.get(i).getLabel();

         if(sLabel != '' && sLabel.indexOf('hidden')<0) { //--RDS Apr2018 hide hidden variables

               var displVal=vs.get(i).getDisplayValue().trim();

               var displVal_len=displVal.length();

                

             if (displVal.length()!=0){  //--RDS Apr2018 dont display empty variables

                 template.print('     ' +  sLabel + " = " + vs.get(i).getDisplayValue() + "\n"); 

              }

        }

      }

  }

</mail_script>
