WP Page will not display ‘tags’

2.9.2
I have a WP Page that is using a template (for all archives) that already displays monthly and categories:
‘<h2 class=”browse”>By Month:</h2>

<?php wp_get_archives(‘type=monthly’); ?>

<h2 class=”browse”>By Category:</h2>

<?php wp_list_categories(‘title_li=0’); ?>

‘

This works perfectly.

I am trying to get one more line to display By Tag:
,
<h2 class=”browse”>By Tags:</h2>

<?php get_the_tag_list(); ?>

‘
I have used several different tag codes and nothing works.

As this is a Page and there is not loop, is that why?
But if that is the case why do the monthly and category work?

thanks
