You have fundamentally misunderstood the way XLST variables work, I'm
afraid. XSLT is not a sequential programming language with assignment
statements, it is a functional language in which you must express the output
you want as a function of the input. Don't think about accumulating the
total as you go along, think about calculating it at the point it is needed,
using XPath expressions such as "sum(../item/price)".
