Firebug Error: e is not defined

Hi,

I'm using the latest version of DayPilot Lite. I'm trying to handle the event click events on the client side using the code from the tutorial section but the event object is not being instantiated.

<asp:XmlDataSource ID="XmlDataSource1" runat="server" DataFile="~/App_Data/TestingData.xml">
</asp:XmlDataSource>
<DayPilot:DayPilotCalendar ID="DayPilotCalendar2" runat="server" DataSourceID="XmlDataSource1"
DataTextField="name" DataValueField="id" StartDate="2007-01-01" TimeFormat="Clock12Hours"
DataStartField="Start" DataEndField="End" Days="7" EventClickHandling="JavaScript"
EventClickJavaScript="window.open('PopupDetail.aspx?id=' + e.value() + '&tag=' + e.tag(),
'PopupDetail','width=400,Height=400,top=200,left=200');"></DayPilot:DayPilotCalendar>

Please let me know where I'm going wrong.

Thanks
