title: Substitution tag only outputting first word
body: <p>I have the following perl mason code:</p>
  
  <pre><code>% my $var = "San Diego";
  &lt;input type="text" value=&lt;% $var %&gt; disabled /&gt;
  </code></pre>
  
  <p>However, when I do this, the value of the textfield only gets set to the first word. So in this case, it gets set to "San".  How can I fix this?</p>
