Isaac  
This client has a GTM on their site. 
However, I went ahead and created a new one so when you get a chance, please add the following code to the site. 
Thanks. 


<!-- Google Tag Manager -->
<script>(function(w,d,s,l,i){w[l]=w[l]||[];w[l].push({'gtm.start':
new Date().getTime(),event:'gtm.js'});var f=d.getElementsByTagName(s)[0],
j=d.createElement(s),dl=l!='dataLayer'?'&l='+l:'';j.async=true;j.src=
'https://www.googletagmanager.com/gtm.js?id='+i+dl;f.parentNode.insertBefore(j,f);
})(window,document,'script','dataLayer','GTM-P7HM348');</script>
<!-- End Google Tag Manager -->

Can you also add the Google analytics code while you are at it Isaac?
My bad for not providing it together. 
Thanks. 

<!-- Global site tag (gtag.js) - Google Analytics -->
<script async src="https://www.googletagmanager.com/gtag/js?id=UA-160828703-1"></script>
<script>
  window.dataLayer = window.dataLayer || [];
  function gtag(){dataLayer.push(arguments);}
  gtag('js', new Date());

  gtag('config', 'UA-160828703-1');
</script>

Hector - No worries brother. Added.

Good morning Isaac. 
Thank you for taking care of this.
