Y'all were absolutely right. My main.html had html, head and body tags
in it, but UserEntry.html, which is the page with the submit button on
it (and was created as a new component), had none of those. I added
them and it works now. I'm actually rather relieved that it wasn't
quite as stupid a user error as I thought! :)
Thanks to all who responded.
