title: I can't get Kivy's button function to work
body: <p><a href="https://i.stack.imgur.com/Df2yy.png" rel="nofollow noreferrer">This is what it looks like when i run it, which is what i want except the flip button does nothing</a>I have tried many fixes for other people but none worked so I am uploading my work in hopes that someone can help me. If you can please comment but you will likely have to put things in the simplest way possible as I don't have a lot of knowledge.</p>
