3rd party booking with Ovatu

Site URL: https://www.thinkliverpool.co.uk/

I'm trying to add my 3rd party booking to my website, I want it to show as the full booking site. When I paste the code into a code block it doesn't work. 

As you can probably tell from this description I'm extremely limited in my website capabilities!

The code Ovatu provide is as follows:

<div id="bookapp-timetable-widget"></div>
<script type="text/javascript">
!function(e,t,n){var u=n.queue||[];e.BookAppWidgetReady=n=function(e){n.queue.push(e)},n.queue=u;var o="script",a=t.createElement(o),i=t.getElementsByTagName(o)[0];a.src="https://cdn.book.app/embed/v1.js",a.type="text/javascript",a.async=!0,a.addEventListener("load",function(){for(;n.queue.length;)n.queue.shift()()},!1),i.parentNode.insertBefore(a,i)}(window,document,window.BookAppWidgetReady||function(){});
BookAppWidgetReady(function () {
    BookApp.widget('#bookapp-timetable-widget', 'THINKLIVERPOOL', { initial: BookApp.Page.Timetable });
});
</script>

What am I doing wrong? 

Hi,

Did you add to Code Injection or Code Block? If Code Block, which page?
