Error. Metoda nie statyczna

To wszystko co tam wklepałem to przepisałem z książki więc nie piszcie mi czegoś w stylu cały kod do wyrzucenia albo zacznij od aplikacji z interfejsem tekstowym albo najlepiej od pracy na kasie w biedronce.

Error wygląda tak a autor twierdzi że nie powinno nic być bo wszystko było wielokrotnie sprawdzane. Sprawdzałem czy się gdzieś nie pomyliłem ale nie zauważyłem niczego.

Error 2 An object reference is required for the non-static field, method, or property 'Windows.UI.Xaml.Media.Animation.Storyboard.Begin()' R:!!!Projekty_c#\Ratuj ludzi\Ratuj ludzi\MainPage.xaml.cs 81 9 Ratuj ludzi

w załączniku dodaje jeszcze fote. I pokornie proszę o pomoc.
