    //Type appropriate comment here, and begin script below

      var cat_id = gel('sysparm_item_guid').value.toString();

      //Check if attachment is available

      var gr = new GlideRecord('sys_attachment');

      gr.addQuery('table_name','kb_knowledge');

      gr.addQuery('file_name','test.dotx');

      gr.query();

      if(gr.next()){
