Undefined variable when checking if variable is defined in Kohana view
<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 ]<br>
  <code>1 &lt;h3&gt;Add&lt;/h3&gt;</code><br>
  <code>2 &lt;?php if( $errors ): ?&gt;</code><br>
  <code>3 &lt;p&gt;&lt;?=$errors?&gt;&lt;/p&gt;</code><br>
  <code>4 &lt;?php endif; ?&gt;</code></p>
</blockquote>

<p>How is my checking not valid?</p>
