Script problems. I installed You Can Javascript and Raw HTML capability

I have a script that is not showing up on either a page or a post. I have installed plugins both (You Can Javascript ) and (Raw HTML capability)
But this script is not showing up.
<script class=’yext-synd-YGaTfP5B8Uc=’>
(function () {
var el = document.createElement(‘script’);
el.async = true;
el.src = ‘//s.yext-listings.com/yext?aid=YGaTfP5B8Uc%3D&city=mesa&state=AZ&zip=&latitude=&longitude=&category=&r=’ + new Date().getTime();
(document.getElementsByTagName(‘head’)[0] ||
document.getElementsByTagName(‘body’)[0]).appendChild(el);
})();
</script>

Thanks in advance for someones help.
