I have view which name is thanks and I want to show this view after click submit , but its encounter with error like this:The webpage cannot be found 
Here is my code:

```
 public class HomeController : Controller
    {
        public ViewResult Index()
        {
            int hour = DateTime.Now.Hour;
            ViewBag.greeting = hour < 12 ? "Good Morning" : "Good Afternoon";
            return View ("MyView");
        }
        [HttpGet]
        public ViewResult RsvpForm()
        {
            return View("RsvpForm");

        }
        [HttpPost]

        public ViewResult RsvpForm(GuestRespons GuestRespons)
        {
            Repository.AddResponse(GuestRespons);
            return View("Thanks", GuestRespons);

        }

    }

```

and this is my view :

```
@{Layout = null;
}
<!DOCTYPE html>
<html>
<head>
    <meta name="viewport" content="width=device-width" />
    <title>
        Thanks
    </title>
</head>
<body>
    <p>
        <h1>
            thank you,@Model.Name!
        </h1>

        @if (Model.WillAttend== true)
        {
            @:it's great that you are comming.we will see you soon.
        }
        else
    {
        @:Sorry to hear that, but Thanks for letting us to know.     
    }
    </p>
    <p >
        click <a asp-action="ListResponses">here</a> to see who is coming.
    </p> 
</body>
</html>

```

And this one is my button which should show thanks view:

```
@model FuturGoals_partyinvites_.Models.GuestRespons

@{
    Layout = null;
}
<!DOCTYPE html>
<html>
<head>
    <meta name="viewport" content="width=device-width" />
    <title>RsvpForm</title>
</head>
<body>
    <form asp-action="RcvpForm" method="post">

        <p>
            <label asp-for="Name">Your Name:</label>
            <input asp-for="Name" />
        </p>
        <p>
            <label asp-for="Email">Your Email:</label>
            <input asp-for="Email" />
        </p>
        <p>
            <label asp-for="phone">Your Phone:</label>
            <input asp-for="phone" />
        </p>
        <p>
            <label>Will you come?</label>
            <select asp="WillAttend">
                <option value="">Choose an option</option>
                <option value="true">Yes</option>
                <option value="false">No</option>
            </select>
        </p>
        <button type="submit">Submit RSVP</button>
    </form>
</body>
</html>

```

well I don't know how get exception in mvc , I think problem should be with this line:

```
<button type="submit">Submit RSVP</button>

```

Thanks in advance.
