title: Windows Phone Navigation code error
body: <p>where am I going wrong here?</p>
  
  <pre><code>private void lstCars_SelectionChanged(object sender, SelectionChangedEventArgs e)
  {
      string currCar = (sender as ListBox).SelectedItem as string;
      NavigationService.Navigate(new Uri("/ViewCarDetails.xaml?info=" + currCar, UriKind.Relative));
  }
  </code></pre>
  
  <p>here is the page im trying to navigate to</p>
  
  <pre><code>        public ViewCarDetails(string registrationNum)
      {
           //stuff
      }
  </code></pre>
  
  <p>and here is the code that the program jumps to when I get an error (in App.xaml.cs)</p>
  
  <pre><code>        private void RootFrame_NavigationFailed(object sender, NavigationFailedEventArgs e)
      {
          if (System.Diagnostics.Debugger.IsAttached)
          {
              // A navigation has failed; break into the debugger
              System.Diagnostics.Debugger.Break();
          }
      }
  </code></pre>
