.Net MVC ActionLink inside a Button not working

Question

I have an action link inside a button that doesn't seem to be working:

<div style="position:absolute; top:0px; right:60px;">
    <button class="btn-top btn-vitae shadow-bottom">
        <a href="/Help" target="_blank">Help</a>
    </button>
</div>

The link is supposed to go to ActionResult Index in the HelpController:

public class HelpController : Controller
{
    //
    // GET: /Help/

    public ActionResult Index()
    {
        return View();
    }
} 

Am I missing something?

Answer 1

if memory serves you need to swap them

<a href="@Url.Action("Index", "Help")"><input type="button" class="btn-top btn-vitae shadow-bottom" /></a>
