Now this is getting clumsy. You should do not do this on client side. Use GlideAjax, and do all the glideRecord queries on server side and return the values. Go thru these links

  g_form.clearOptions('vs_location'); // Clear options from the Location select box

  var gp = new GlideRecord('core_country');

  gp.addQuery('name', newValue);

  gp.query(callBack);

  function callBack(gp){

  while(gp.next()){

  countrycode = gp.iso3166_3;

  // get locations using country from the u_citrix_office_locations name

  var gp1 = new GlideRecord('u_citrix_office_locations');

  gp1.addQuery('u_country_code', countrycode);

  gp1.query();

  gp1.query(callBack1);
