displaying subtotal of a basket

[chilita]

Please, I would like to know how can I display in a module (to put below de menu) the subtotal of the basket, I like this example http://www.rootsdirect.co.uk/index.php?page=shop.product_details&flypage=flypage-ivo.tpl&product_id=88&category_id=2&vmcchk=1&option=com_virtuemart&Itemid=73
"Your shopping basket" module.

I am preparing a shop online for a cooperative and it woul work very well.

Thanks very much.
