Hi all can anyone tell me where to edit this :-

I changed my front page to show categories and now it says "products" as the header . I have used firebug and found it is being drawn from here :-

Line #18 : <h1 id="indexCategoriesHeading"><?php echo HEADING_TITLE; ?></h1>

Now before i just edited index.php and changed the "you have succesfully"

// This section deals with displaying a subcategory
/*Replace this line with the headline you would like for your shop. For example: 'Welcome to My SHOP!'*/
define('HEADING_TITLE', 'Welcome to Gloopy');

I used the developers tool kit and it came up as /templates/tpl_index_categories.php

now when i open that i see where its being called from

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

but where is the "Products" bit to edit.

p.s i used the developers toolkit to search for "products" and there are thousands lol so can someone please help
