Tags Help

I am using ‘DailyPress’ theme form BlogOH!blog, a well mentioned site here at WP. On the main index page the post have the time,category, and add comment. As you can see in code below I tried adding the tags also so they would display. THEY DI”D NOT in main index page but did on lower hierarchy pages.

Can someone please fill me in why this may not work on main index.page.

<strong><p class="postinfo"><span class="upper"><?php the_time('M j, Y') ?></span> <span class="category"><?php the_category(', ') ?></span> <span class="postinfo"><?php the_tags( 'Tags: ', ', ', ''); ?></span><span class="comment"><?php comments_popup_link('Leave a comment', '1 Comment', '% Comments'); ?></span></p></strong>
