Adding the_author_firstname() to archive.php

Hi All.

New user and well please with the product and the support here ??

I added the following Template tag to archive.php

<?php /* If this is an author archive */ } elseif (is_author()) { ?>
<h2 class=”pagetitle”>Author Archive –

<?php the_author_firstname(); ?>

</h2>

but it is not showing up when I browse from a link generated by

<?php the_author_posts_link(‘namefl’); ?>

Any ideas?

Thanks

Steve
