Shows My Account ONLY After Login

[tuppergreen]

Hi,

 

I want to have My Account appear only after Login. There isn't any error message after I edit includes/header.php as below but My Account is still appearing before customer Login. Without error message, I don't even know whats wrong, can you help please? Thanks!

 

 

	<td align="right" class="headerNavigation"><?php 
if (tep_session_is_registered('customer_id')) 
{ 
?>
<a href="<?php echo tep_href_link(FILENAME_LOGOFF, '', 'SSL'); ?>" class="headerNavigation"><?php echo HEADER_TITLE_LOGOFF; ?></a>  |  
<a href="<?php echo tep_href_link(FILENAME_ACCOUNT, '', 'SSL'); ?>" class="headerNavigation"><?php echo HEADER_TITLE_MY_ACCOUNT; ?></a>  |  <?php 
} else { ?>
<a href="<?php echo tep_href_link(FILENAME_LOGIN, '', 'SSL'); ?>" class="headerNavigation"><?php echo HEADER_TITLE_LOGIN;} ?></a>
