title: Undefined variable when checking if variable is defined in Kohana view
body: <p>I'm running into this error when loading up my view:</p>
  
  <blockquote>
    <p>ErrorException [ Notice ]: Undefined variable: errors<br>
    APPPATH\views\admin\category\add.php [ 2 ]  </p>
  </blockquote>
  
  <pre><code>&lt;h3&gt;Add&lt;/h3&gt;  
  &lt;?php if( $errors ): ?&gt;
  &lt;p&gt;&lt;?=$errors?&gt;&lt;/p&gt;
  &lt;?php endif; ?&gt;
  </code></pre>
  
  <p>How is my checking not valid?</p>
