title: TypeError: must be real number, not none type plus more errors
body: <p>Oh, goodness. I've become a regular here. I have all of my code but it's weird because I'm trying my best but I cannot seem to get it to work. I've tried rewriting parts of it and even making minor changes but it just won't work. At all.</p>
