收到MVC路由问题404

Question

I am trying to call an action method through ajax but am getting a 404. To illustrate, the following is my ajax:

  $.ajax({
            type: "GET",
            url: "/Product/LandingPage",
            data: {trackingCode: trackingCode, productId: productId},
            success: function (data) {
                alert("I worked!");
            }
        });

From alerting out the paramters I can see both trackingCode and productId are being successfully set so that's not the issue. I thought, to test this, I should be able to direclty call the URL like so:

http://www.mywebsite.com/Product/LandingPage?trackingCode=fgdfg&productId=213456

However, when I try that I get a 404 error, so maybe the routing isn't working. I've added the following route:

            routes.MapRoute(
           "Product_LandingPage",
           "Product/LandingPage",
           new { controller = "Product", action = "LandingPage" }, new {  trackingCode = UrlParameter.Optional ,productId = @"\d+" });

But I still get a 404. This is my Product controller method:

 [AcceptVerbs(HttpVerbs.Get | HttpVerbs.Head)]
    public ActionResult LandingPage(string trackingCode, int productId)
    {
        //Some magic in here
    }

I've a feeling I'm missing something obvious here. Any ideas as to why I'm getting a 404?

Note this could be some other code causing an issue, I just want to sanity check what I'm doing to rule out a stupid mistake on my part.

Using Phil Haacks route debugger I found the issue, it was caused by another route, higher up the chain of route command. Restructuring has sorted this out. Thanks for all help.
