title: The output for "createHtmlOutputFromFile" is very literal and not utilizing the code I wrote
body: <p>So I wrote a script that has an HTML file associated with it. The script is long so I won't post it, but at the end I have this:</p>
  <pre><code>  // Send HTML content in email
  
    var htmlBody = HtmlService.createHtmlOutputFromFile(&quot;AttendanceInfractionsHTMLTemplate&quot;).getContent();
  
    MailApp.sendEmail({
      to: Session.getActiveUser().getEmail(),
      subject: 'EI Email',
      htmlBody: htmlBody,
    });
  }
  </code></pre>
  <p>The problem is that when I receive the email in my inbox, the code in the HTML template hasn't run successfully and it shows the scriptlets in all their glory, such as my if/else statements and all that. This doesn't happen when I deploy a test of the HTML file. Any ideas? Can't seem to find anything about this in the Google Apps Script reference guide.</p>
