title: Concatenating a variable + string in Jade file
body: <p>I am passing in a session variable from my mongodb session store in an Express for Node.js web app like this:</p>
  
  <pre><code>exports.dashboard = function(req, res){
      res.render('dashboard', {pref: req.session.layoutpref});
  }
  </code></pre>
  
  <p>Then, in my Jade file I'm trying to assign the value of <code>pref</code> to the css link like this, but I'm getting a syntax error:</p>
  
  <pre><code>head
          title #{title}
          link(rel='stylesheet', href='/stylesheets/' + #{pref} + '.css')
  </code></pre>
  
  <p>I'm almost certain the problem is in my concatenation of <code>pref</code> into the location of the css file to be used. Any ideas how to fix this?</p>
