need the tag page to act/display just like the category page….

when you click a category page on my site (here’s one: http://ankatankdesign.com/makes/some/print/ )

it displays stuff based on whats in my “sidebar-right.php”

when you click a tag, (for example: http://ankatankdesign.com/makes/tag/film/) i’ve got it set up to do the exact same thing, but it doesn’t give me anything. I’ve tried to modify the sidebar-right.php code to inlcude tag code, but I keep breaking it, so i’ve removed it, hoping someone can tell me what I need to do to make it work. (i do not know php well, just what i am learning from creating this wordpress site…)

this is the code in my category.php:

<?php get_header() ?>
<?php get_sidebar('right'); ?>
<?php get_footer() ?>

this is the code in my tag.php:

<?php get_header() ?>
<?php get_sidebar('right'); ?>
<?php single_tag_title(' tagged ' , 'true' ); ?>
<?php get_footer() ?>

here’s the code in my sidebar-right.php:

<div id="secondary" class="sidebar-CAT">

		<?php $cat_title = single_cat_title('',false);
            if (!$cat_title=='') {

            if ( !empty($categorydesc) ) echo apply_filters( 'archive_meta', '<div class="archive-meta">' . $categorydesc . '</div>' );
                }
         ?> 

		<?php  

        if(is_single()) {

            $category = get_the_category();

			query_posts('posts_per_page=-1&category_name=' . $category[0]->cat_name);

        } else {

            query_posts('posts_per_page=-1&category_name=' . single_cat_title(false, false));

        }

        while (have_posts()) : the_post(); ?>

       		<div id="sidebarCAT"><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title(); ?>"><img src="http://www.aaank.com/images/post_thumbs/<?php $values = get_post_custom_values("theThumb"); echo $values[0]; ?>" alt="" /></a>

            <!--<div class="underThumb">< ?php the_date('m d Y', '', ''); ?></div>-->
            <div class="underThumbTxt"><?php if (strlen($post->post_title) > 15) {
echo substr(the_title($before = '', $after = '', FALSE), 0, 15) . '...'; } else {
the_title();
} ?></div>

           </div>

		<?php endwhile; wp_reset_query(); ?>

       	<br style='clear:both;' />	

</div>

can anyone tell me how i should to modify the sidebar-right.php code so that if a tag is clicked, it shows, tags results just like it shows category results? (i realize that there will no longer be a selected nav item, and i’m ok with that.)

thanks in advance!
