title: When should variables be quoted in GTM custom html tag?
body: <p>I am trying to implement facebook pixel via GTM, and I am hitting a few oddities. </p>
  
  <p>I am implementing via custom html tag, and If i dont quote the variables, the gtm debugger shows them as <code>google_tag_manager["&lt;ID&gt;"].macro(\'gtm123123123\')</code>in the debugger, instead of the value itself. If i surround the use of the variable with quotes, I see the value itself. </p>
  
  <p>If the <code>{{User Email}}</code> is translated into javascript code as i am seeing, I presume quoting isnt required?</p>
  
  <p>If I need to quote, how would I write code like? <code>em: ({{User Email}} || "").toLowerCase(),</code></p>
  
  <p>Which is recommended? How to decide?</p>
  
  <p>Also the debugger surrounds the entire tag in a '' is this expected? </p>
