I have a custom post type called portfolio.  I need a previous/next link WITHOUT a plugin.  Anybody have a solution?


Example post:
http://themeforward.com/demo2/archives/portfolio/boat

    <?php get_header(); ?>
    
    <!-- Begin wrap -->
    <div class="clear">
    <div id="full_container">
    <div id="content2">
    <div id="content">
    
    <!-- Grab posts -->
    <?php if (have_posts()) : ?><?php while (have_posts()) : the_post(); ?>
    
    <!-- Post title -->
    <h1>
    	<?php the_title(); ?>
    </h1>
    
    <!-- The post -->
    <?php the_content(); ?>
    
    <!-- Tags -->
    <h3 class="tags">
    	<?php the_tags('Tags ',' / ','<br />'); ?>
    </h3>
    
    <!-- End wrap -->
    </div>
    
    <!-- Next/Previous Posts -->
    <div class="mp_archive2">
    <div id="more_posts">
    	<div class="oe">
    		<?php previous_post_link('%link', '« Previous post', TRUE); ?>
    	</div>
    
    	<div class="re">
    		<?php next_post_link('%link', 'Next post »', TRUE); ?>
    	</div>
    </div>
    </div>
    
    <?php endwhile; else: ?>
    <p>No matching entries found.</p>
    <?php endif; ?>
    </div>
    </div>
    </div>
    </div>
    <?php get_footer(); ?>
