I believe this is demonstrated in the cart code, which is located at 
yourcat/templates/components/cart. The [summary ..] tag has a parameter for 
returning the accumulated value, which you should be able to see in 
practice there.

Kevin - examples of this are all over the foundation demo, plus you have 
the Interchange tag reference at your disposal: take a look at the docs for 
[value ..], [var ..], [scratch ..], [cgi ...] and [data ...], among others.
