Cannot get Embedded Availability calendar to show

I have generated the embed availability calendar script, but I am unable to get it to display in my test website.
I have embedded the script directly, which is what the directions in the system say, but nothing will show in my page.

Is there a specific way to get this script to work, that I am missing?

The code I generated and embedded directly into my webpage was:

<div id="sr-embed"></div>
<script>
(function (w, d) {
var s = d.createElement('script');
s.src = 'www.wandjoo.com/media/plg_solidres_hub/assets/js/embed.js';
s.async = 1;
s.addEventListener('load', function () {
_srembed.load(10, 'en', {"bgColor":"#fa0f0f","fontColor":"#fff5f5","inputBg":"#ffffff","buttonBg":"#000000","buttonColor":"#bdacac","target":"_parent"});
});
d.getElementsByTagName('head')[0].appendChild(s);
})(window, document);
</script>
