title: Server variable not recognized on Google Tag Manager with "HTML Custom" type tag
body: <p>I want to put a GTM container on my webpage, just to add scripts without modify html of my page (I will no longer have acces).</p>
  
  <p>1)Currently, I just put the GTM code after , created a tag on my GTM account (tag type = GA), added UA-XXXXX-Y of my GA account : it's work, I can see visit from my GA acc.</p>
  
  <p>2)Then, I tried to change the type of my tag created on GTM : I choose Custom HTML type, and I put the code given by GA (with correct UA)</p>
  
  <pre><code>&lt;script type="text/javascript"&gt;
  var _gaq = _gaq || [];
  _gaq.push(['_setAccount', 'UA-XXXXX-Y']);
  _gaq.push(['_setDomainName', 'example.com']);
  (function() {
  var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true;
  ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js';
  var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(ga, s);
  })();
  &lt;/script&gt;
  </code></pre>
  
  <p>It's work too, I see visit from GA interface</p>
  
  <p>3) I want to modify the code given by GA, especially add trackPageview with param (using server variable, here's my problem...)</p>
  
  <p>So I just modified code that I used in 2), just adding :</p>
  
  <pre><code>_gaq.push(['_trackPageview', '/Page1/$!{VAR}/Page2/$']);
  </code></pre>
  
  <p>and it doesn't work.</p>
  
  <p>Did I do something wrong? Should I use macro?</p>
  
  <p>Thanks</p>
