You hit the nail on the head. So I'm really just misunderstanding the
tutorial. And of course, looking at the code now it makes sense,
because it only redirects to the second page if there is actually a

Thanks, folks. It's a self-facepalm. But there will probably be
others, so don't expect this to be my last somewhat clueless question!
