Hi Lynn,
put following code or some of the earlier examples to your template_header.php. If you want your cart to be for example inside navCatTabsWrapper, then put this code inside those divs and just under the navCatTabs closing div. Or you can put it anywhere you like.
HTML Code:
<div id="headerCart">
<ul class="hCart">
<li><?php echo $_SESSION['cart']->count_contents() . HEADER_TITLE_CART_ITEMS ;?></li>
<li><?php echo HEADER_TITLE_CART_AMOUNT . $currencies->format($_SESSION['cart']->show_total());?></li>
<li class="cartLink"><a href="<?php echo zen_href_link(FILENAME_SHOPPING_CART, '', 'NONSSL'); ?>"><?php echo HEADER_TITLE_CART_CONTENTS; ?></a></li>
</ul>
</div>
If you are using code above, you have to define those TEXTs in languages/english/your_template/header.php.
Depending of where you put your code, you need to use css to float new #headerCart div to its place. And if above code is used, css also needs this
#headerCart ul li{
display: inline;
}
to show list inline.
