Lucky Orange Tracking script

trying to set up the tracking system for lucky orange the tracks activity on my website. They have a script they want me to install on each page that I want to be tracked. When I look at the pages of the highend wp theme there are no head scripts in any of the pages I looked at. I went to the general settings and under the high-end options, I see the field for the tracking scripts. I did paste the script in but I’m not sure is this the correct place for it. Here is the script that they would like me to add.
<script type=’text/javascript’>
window.__wtw_lucky_site_id = 0;

(function() {
var wa = document.createElement(‘script’); wa.type = ‘text/javascript’; wa.async = true;
wa.src = (‘https:’ == document.location.protocol ? ‘https://ssl&#8217; : ‘http://cdn&#8217;) + ‘.luckyorange.com/w.js’;
var s = document.getElementsByTagName(‘script’)[0]; s.parentNode.insertBefore(wa, s);
})();
</script>

If this is the inappropriate place for the script or I need to put it on every page can you advise please?
