Get guid of lookup value after fetching it via fetchxml

Hi,

i am retrieving a record using fetchxml based on a guid. The fetch works perfectly but i cannot get the values of lookup attribute.

here is my code

var _oService;
	var _sOrgName = "CRMTEST";
	var _sServerUrl =Xrm.Page.context.getServerUrl();	
	var sFetch = "<fetch version='1.0' output-format='xml-platform' mapping='logical' distinct='false'>"+"<entity name='new_mbasession'>"+"<attribute name='new_mbasessionid' />" +"<attribute name='new_name' />" +"<attribute name='new_university'/>"+"<order attribute='new_name' descending='false' />"+"<filter type='and'>"+"<condition attribute='new_mbasessionid' operator='eq' value='" + id2 + "' />"+"</filter>"+"</entity>"+"</fetch>";

	_oService = new FetchUtil(_sOrgName, _sServerUrl);
	_oService.Fetch(sFetch, myCallBack);
}
	
	function myCallBack(results)
{
	var university = results[0].attributes["new_university"].value;     
}

how do I get the guid of the lookup attribute new_university?? It shows undefined in this case.

and if I read any other attribute it shows the desired value.

Plz Help

Thanks
