changing the position of greeting text

[zzahid]

Hi, I want to know that how I can change the position of the greeting text in the main page. Currently I'm working on a website:
http://eyeprinters.com/shop/

I want the greeting text to be positioned above the navigation bar on the right corner. I'm not an expert but I had tried to do something from my own, I had cut the text from tpl_index_default.php and pasted it to the file tpl_header.php, the code is:

<?php if (SHOW_CUSTOMER_GREETING == 1) { ?>
<h2 class="greeting"><?php echo zen_customer_greeting(); ?></h2>
<?php } ?>

the problem doing this is that in every page other than the main page it is showing TEXT_GREETING_GUEST where the greeting should be in the main page.

I don't know where am I wrong.
