title: undefined variable in Smarty
body: <p>I'm using DooPHP and I'm generating a security token for my form to protect against csrf attacks. I'm assigning the token to a smarty variable and I can see that it is displayed in the source - so it is available. When I submit the form though, it throws out an error saying:</p>
  
  <pre><code>Undefined variable: secToken
  See file C:\wamp\www\korysdoo\protected\class\smarty\sysplugins\smarty_internal_data.php
  Error on line 291 $x = $$_variable;
  </code></pre>
  
  <p>Any ideas what can be wrong? I can see that the value of secToken is being posted to an appropriate function.</p>
