Method Error : 12030

While I was trying to make this sample work
http://www.asp.net/AJAX/AjaxControlToolkit/Samples/Walkthrough/CCDWithDB.aspx
The following error appeared
1) Method Error 12030
2) Method Error 12031
3) Method Error 500
How I solved it??
1) Specify [System.Web.Script.Services.ScriptService()] before Class defination in Web Service.
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.Web.Script.Services.ScriptService()]
public class CarData : WebService
2) Check the name of method is correct as it is defined in Web Service and specified in Cascadedropdown.
3) Install Fiddler program. http://www.fiddlertool.com/Fiddler2/version.asp . It is an excellent Http Debugger.
Hope this help fellow visitors
