It means that MVC found two action methods with the same name and is confused. You can remove the ambiguity by:

Adding a HTTP method attribute:

[HttpGet] // This method will be called only on GET http requests
public ActionResult Index() { ... }

[HttpPost] // This method will be called only on POST http requests
public ActionResult Index(int id) { ... }

Specifying an action name:

// This method will be called for /ControllerName/Index requests
public ActionResult Index() { ... }

[ActionName("Index2")] // This method will be called for /ControllerName/Index2 requests
public ActionResult Index(int id) { ... }

The error you are getting tells that ASP.NET MVC has found two actions with the same name and can't chose which to use.
