How to get META description to show?

[j*z]

I'm using a custom theme I made years ago. Seems GS no longer supports this 

PHP Code:

<?php get_page_meta_keywords(); ?>

 in the meta description. My pages have no meta description, despite having filled in a meta description from within Admin (page options).

I'm running version 3.3.10 but will upgrade to 3.3.13 shortly.
