Single page nav vs. main page nav

Hello,

I am building my theme from scratch, so I have basically built what I am working on from the ground up.

In my header I have the following:

• <?php wp_title(”); ?>
• #comments”><?php comments_number(‘no comments yet’,’1 comment’,’% comments’)?>

<li id=”prev”>
<?php previous_post_link(‘%link’, ‘«’); ?>
<?php if(!get_adjacent_post(false, ”, true)) { echo ‘<span>«</span>’; } // if there are no older articles ?>

<li id=”next”>
<?php next_post_link(‘%link’, ‘»’); ?>
<?php if(!get_adjacent_post(false, ”, false)) { echo ‘<span>»</span>’; } // if there are no newer articles ?>

My issue is, it works fine on the single post pages, but if you come in directly to the main blog page, not everything displays or works properly. If I am understanding things correctly, this chunk needs to be ‘in’ the loop to work. However when I move the start of the loop, all I get is errors.

Any ideas/thoughts?

Here are the two “pages” of working/not completely working.

https://brainofj.com/blog/2009/11/another-post/ ( single post with the nav working as I want it to on all pages)

Thanks
