Ahh. For it to work properly both codes need to be in the same template. Since your link is in the Header template remove your code in the navbar template. Then at the bottom of your Header template after:
Add
Code:
<if condition="$show['popups']">
<!-- Audio popup menu -->
<div class="vbmenu_popup" id="Audio" style="display:none">
<table cellpadding="4" cellspacing="1" border="0">
<tr><td class="thead">Page</td></tr>
<tr><td class="vbmenu_option"><a href="http://www.uponsunnah.com/lectures.php">Lectures</a></td></tr>
<tr><td class="vbmenu_option"><a href="http://www.uponsunnah.com/quran.php">Qur'an</a></td></tr>
<tr><td class="vbmenu_option"><a href="http://www.uponsunnah.com/arabic.php">Learn Arabic</a></td></tr>
</table>
</div>
<!-- / Audio popup menu -->
</if>
BTW...If the links you are calling are within your domain, not an external domain, I suggest removing the "http://www.uponsunnah.com". It's just added server resources when you loop internal links.
