Adding custom field to Event

Hello, I’m trying to add a new custom field to the event box, but it seems to add an extra section that keeps saying “Undefined”. I want to add a section called “Organizer” which is not editable by users

Attached is a picture of what i mean (I want that “Undefined” Gone)
And here is my code

function init() {
	
		scheduler.form_blocks["campus_editor"]={
			render:function(sns){
				return "<div class=\"dhx_cal_ltext\" style=\"height:60px;\"><textarea rows=\"3\" cols=\"25\" readonly=\"readonly\">This is a readonly description </textarea></div>";
			},
			set_value:function(node,value,ev){
				node.childNodes[1].value=value||"";
				node.childNodes[4].value=ev.details||"";
			},
			get_value:function(node,ev){
				ev.location = node.childNodes[4].value;
				return node.childNodes[1].value;
			},
			focus:function(node){
				var a=node.childNodes[1]; a.select(); a.focus(); 
			}
		}	
	
		
		scheduler.form_blocks["campus_organizer"]={
			render:function(sns){			
				return "<label id='Organizer' style='height:50px;'>Organizer:</label><label id='name'></label>";
			},
			set_value:function(node,value,ev){ //this is a place holder
				node.firstChild.value=value||"";
				node.firstChild.disabled = ev.disabled;
			}
		}
		
		scheduler.config.lightbox.sections=[	
			{ name:"organizer", height:100,map_to:"",type:"campus_organizer" },
			{ name:"description", height:200, map_to:"text", type:"campus_editor", focus:true },			
			{ name:"time", height:72, type:"time", map_to:"auto"}	
		]
	
	
		scheduler.config.multi_day = true;
		
		scheduler.config.xml_date="%Y-%m-%d %H:%i";
		scheduler.init('scheduler_here',new Date(2010,0,10),"week");
		scheduler.load("../scripts/dhtmlxScheduler/common/events.xml");
		
		
		
	}


Hello,

From our documentation:

You simply need to set up locale for your new section:
scheduler.locale.section_organizer = “Organizer”;

Best regards,
