Added quick cart in template - not displaying items on all pages
I'm trying to include a quick cart on each page of a store I'm building. I've added the quick cart code into the site template and made sure the include file (WA_eCart/ycCart_PHP.php) is written in an locked region of the template so that it's included on every page, which it is.
However, every page in the site apart from one states that the cart is empty, even when there are products in it.
I've attached a zip file with the home page of the site (which doesn't display the cart total or item count) and the only page in the site that does display the cart total and item count.
I don't understand why it works on this one page, but no others, when I know the include file(WA_eCart/ycCart_PHP.php) is included on every page.
Any help is appreciated
