Help with Custom Menu

Hello all!

I have a website where the top navigation is ‘dynamic’ based on how the pages are laid out in the hierarchy.

We now need to replace this with a custom menu that I’ve built, however, when I implement this, the nav completely disappears. Can somebody help?

<?php
//wp_list_pages(‘title_li=’);
wp_nav_menu( array( ‘menu’ => ‘Main Nav’) );
?>

The website is https://www.westbridge.org if that helps.

Thanks so much!
