Your above code works perfectly (of course), now I need to give a grandtotal
of all the prododucts I calculated above.  Does that mean that I
need to loop through the table twice once to create all those
subtotals as above and again to get the sum of all of them with a recursive template?
Not sure how to implement this ....

Nope I am using xsltproc for now because of the reason below.
