Ok, thanks clydejones.

I added that to the bottom, under /* ------ Navigation bar -----*/ etc etc.

Now, with the tpl_header.php file, how do I add it?
This is the original file here:

Code:
<?php
/**
 * Common Template - tpl_header.php
 *
 * this file can be copied to /templates/your_template_dir/pagename<br />
 * example: to override the privacy page<br />
 * make a directory /templates/my_template/privacy<br />
 * copy /templates/templates_defaults/common/tpl_footer.php to /templates/my_template/privacy/tpl_header.php<br />
 * to override the global settings and turn off the footer un-comment the following line:<br />
 * <br />
 * $flag_disable_header = true;<br />

?>
<?php

	
  // Display all header alerts via messageStack:
  if ($messageStack->size('header') > 0) {
    echo $messageStack->output('header');
  }
  if (isset($_GET['error_message']) && zen_not_null($_GET['error_message'])) {
  echo htmlspecialchars(urldecode($_GET['error_message']));
  }
  if (isset($_GET['info_message']) && zen_not_null($_GET['info_message'])) {
   echo htmlspecialchars($_GET['info_message']);
} else {

At the moment, I'm just replacing the NAVIGATION LINKS section with the HTML I was given, but it's not doing anything.

Also, is the NAVIGATION LINKS the EZ Pages ones, or the normal text based ones that you can turn on (tabs, I think they're called?)


Any help is much appreciated, of course!
