Parse error question

I am getting this error:
Parse error: syntax error, unexpected $end in /home2/nptwozer/public_html/blog/wp-content/themes/blixed-10/functions.php on line 162.

Here is my url: https://www.np2020.org

My code on functions.php is:

<?php

register_sidebar(array('before_widget' => '',
		'after_widget' => '',
