Any idea how to get something like this to work? [closed]

The function esc_html__, it escapes html. the sumbol < is converted into its unicode, which is &lt;, and so on. You can see the wordpress documentation on what it does and how it works.

You need to change esc_html__ to __.

When mixing html with wordpress localization functions its best to use sprintf. But for now just changing the function will do the trick
