Hi,
sorry to say this, but you should never assume that a plugin should work like any another plugin or use references like that, because behind any plugin there is a different developer.
In there you need to paste the whole tracking code that google provides
Example:
<script>
(function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){
(i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),
m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)
})(window,document,'script','//www.google-analytics.com/analytics.js','ga');
ga('create', 'UA-52472672-1', 'auto');
ga('send', 'pageview');
</script>
Otherwise we would have wrote, paste the google analytics tracking ID (not code)
Thx
