Category Page Mods Not Working

[britblaise]

I followed the instructions here for making thumbnails display on category pages and also showing the full post instead of summaries. Nothing happened. It is the exact same. Here is what I changed the code to:

PHP Code:

<?php if( get_post_meta($post->ID, "thumb", true) ): ?>
                                <a href="<?php the_permalink() ?>" rel="bookmark"><img class="thumb" src="<?php bloginfo('template_directory'); ?>/tools/timthumb.php?src=<?php echo get_post_meta($post->ID, "thumb", $single = true); ?>&amp;h=<?php echo get_theme_mod('featured_bottom_thumb_height'); ?>&amp;w=<?php echo get_theme_mod('featured_bottom_thumb_width'); ?>&amp;zc=1" alt="<?php the_title(); ?>" /></a>
                                <?php else: ?>
                                <?php endif; ?>    
            <?php the_content("Read More.."); ?><div class="clear"></div>

What am I doing wrong?
