Hi  people . David Carlisle , I'm Sorry.  I think that I became my
problem in some very complex
 hard to understand.

I translate it this way:  If i have this XML



I Think  through this example you'll understand what I want to do.  

The question: I have Two categories: sport and Pick-up. Ok? 

How can I  using XSL to obtain the Total value by category, in this
case  = 2 ?     Thanks .
