help with nav link sorting..

I’m learning php and wp at the same time so may have missed something.

I want my nav at the top to sort by the edit->page – sort order setting.

I started with:
<?php wp_list_pages(‘title_li=&depth=-1&sort_column=ID’); ?>

and changed it to:
<?php wp_list_pages(‘title_li=&depth=-1&sort_column=menu_order’); ?>

but its still not sorting by the way I note the pages on my site.

Thanks in advance 🙂
