Webservice is undefined

Hello All,


I m constantly getting "Webservice is undefined" error in my javascript code when i get to "WebService.GetInfo(siteid,DisplayResult);" function.
I m using master pages in my website and my script manager is in master page.


To include webservice, I did
<asp:ScriptManager ID="ScriptManager1" runat="server">
<Services>
<asp:ServiceReference Path="WebService.asmx" /></Services>
</asp:ScriptManager>
 
Any solutions or hints !!!!!!!
