adding code for sidebar edit

https://www.miamiartexchange.com/maex_artblog/
I changed my theme to the one shown which does not have a blogroll in its default ver. Changing to sidebar widgets with drag-and-drop breaks it so, I want to keep the default. Howevever, I want to add the blogroll (and call it links) above the META in the right-hand column. I’ve been searching for hours trying to figure out what the “if statement” should be on the function.php page. The more I read, the more confused I get.

I assume this is correct for sidebar.php:
<li id=”Blogroll”>
<h2>Links</h2>

<?php get_links(-1, ‘
• ‘, ‘

‘, ‘ – ‘); ?>

<?php endif; ?>

What goes on function.php (and where) this?

<?php if (is_page() || $contlen >) { ?>
<h2>Blogroll</h2>

<?php wp_list_bookmarks(); ?>

<?php } ?>:

Thank you in advance for any assistance!
