Getting error in this code?

Hello Developers,

I am getting error in this line.
Error message is Compiler Error Message: CS1502: The best overloaded method match for 'DotNetFunda.UrlHandler.GetRouteUrl(System.Web.UI.Page, string, string, string, string)' has some invalid arguments

string returnData = "<a href=\"" + DotNetFunda.UrlHandler.GetRouteUrl(this.Page, 2, int.Parse(autoId),userName,title) + "\" title=\"" + title + "\">" + title + "</a>&nbsp;" + newFlashString;
