I declared both vars at the start of the stylesheet so I do not
know if this makes it a global or local variable.

I just tried the same thing with xalan and the var also went
out of scope (seemingly).

- perhaps i am going about this the wrong way - i need to calcualte the product of the
last two cells in a row viz.

         <row header="phase">
            <cell>
              John Doe
            </cell>
            <cell>
              Engineer
            </cell>
            <cell>
              246
            </cell>
            <cell>
              135
            </cell>
          </row>

This should be so easy to do (maybe it is?).
