Primary Links Disappeared after modifying page.tpl.php

I modified my template to display the primary links in the header section. It works great on my development system but after I upload the entire template with css templates to my site, they do not show up. I verified that all template files uploaded correctly. When viewing the rendered pages source, the primary links section is missing.

Can anyone help?

My code:

  <div id="wrap">
    <div id="header">
<?php if ($site_slogan) { ?><p id="subtext"><?php print $site_slogan ?></p><?php } ?>
<img id="frontphoto" src="<?php if ($logo) { ?><?php print $logo ?><?php } else { ?><?php print base_path(). path_to_theme(); ?>/logo.gif<?php } ?>" width="336" height="70" alt="" />
      <?php if ($site_name) { ?><h1 class="site_name"><a href="<?php print base_path() ?>" title="<?php print t('Home') ?>"><?php print $site_name ?><?php } ?></a></h1>
	  
<?php if ($primary_links) { ?>
        <h2 class="hide"><?php print t("Primary Links:")?></h2>
          <ul id="primary-links">
            <?php foreach ($primary_links as $link) { ?>
              <li><?php print $link?></li>
            <?php }; ?>
          </ul>
      <?php }; ?>
   </div>

......

Thanks
