Syntax Error LINE 1

Hi guys, I am trying to add a ResDiary widget to my website, everytime I go to the custom css and paste the code I get the error message Syntax Error On Line 1... Here's the code, anyone know why this is happening?

<div id="rd-widget-frame" style="max-width: 285px; margin: auto;"></div>

<input id="rdwidgeturl" name="rdwidgeturl" value="https://booking.resdiary.com/widget/FixedSize/TheRose/913?includeJquery=false" type="hidden">
<script type="text/javascript" src="https://booking.resdiary.com/bundles/WidgetV2Loader.js"></script>

The Custom CSS panel is for CSS only, whereas the code you've quoted is HTML so must be added to a Code Block. 

Hi Paul, thanks for your reply I really appreciate it. I've added the code block to the page and added the code but it just says 'script disabled' and does not display the widget button that the code is meant to show.. any idea? Thanks once again

As a security measure, scripts will not run in a code block when you’re logged in. The 'script disabled' message is trying to explain this, but it isn't a very friendly message.

To test the script, visit your site in an incognito browser without logging in.
