Short code displays on site

I put this code in to the html field

<script>var BotStar={appId:"sc3c2a350-6280-41b7-b295-db13ad5d7de4",mode:"livechat"};!function(t,a){var e=function(){(e.q=e.q||[]).push(arguments)};e.q=e.q||[],t.BotStarApi=e;!function(){var t=a.createElement("script");t.type="text/javascript",t.async=1,t.src="https://widget.botstar.com/static/js/widget.js";var e=a.getElementsByTagName("script")[0];e.parentNode.insertBefore(t,e)}();}(window,document)</script>

and pasted the shortcode [WP-Coder id="1"] in my footer, and that’s what displays, at the very bottom of the site.

The page I need help with: [log in to see the link]
