I have some custom taxonomy for a group of posts, and I also have a need to show these posts on a custom page template.  I want to show one post at a time, with pagination so that the user can click through them, like a slide show.  My template correctly grabs the right category and display one (the first) post, but when I try to click through the pagination, it sends me to the archives for the next post.  I want to click "next" and be taken to the next post within in the same page template.  I've working with [this solution][1], but I can't get it to work.

Here's my code, as it is....

    <body <?php body_class(); ?>>
    <div id="full-page">
        <div id="wrap">
            <div id="full-main-col">
                <a href="#" id="share" rel="prettySociable" title="Drag to Share"><img src="<?php echo get_template_directory_uri(); ?>/img/share.png" alt="" /></a>
    
    			<?php if (have_posts()) :
                                while (have_posts()) :
                                the_post(); ?>
                
                                    <div id="page-head">
                                        <?php the_title('<h1>', '</h1>');
                                        if (function_exists('dimox_breadcrumbs')) dimox_breadcrumbs(); ?>
                                    </div>
                
                               <?php endwhile;
                            endif; ?>
                <?php include( TEMPLATEPATH . '/sidebar-right.php' ); ?>
                
    			<?php
                  query_posts( array( 'post_type' => 'fieldtrips', 'fieldtripcategory' => 'elementary-school-aquifer', 'order' => 'ASC', 'posts_per_page' => 1 ) );
                  if ( have_posts() ) : while ( have_posts() ) : the_post();
                ?>
                
                  <h3><?php the_title(); ?></h3>
                  <?php the_content(); ?>
                  
                  <?php previous_post('&laquo; &laquo; %', '', 'yes'); ?> | <?php next_post('% &raquo; &raquo; ', '', 'yes'); ?>
                
                <?php endwhile; endif; wp_reset_query(); ?>
                
            </div>
        </div>
    <?php
    get_footer();
    ?>

Thanks for your help in advance...
