[xsl] XSL: How to Calculate Running Total using Variable within FOR-LO OP?

Subject: [xsl] XSL: How to Calculate Running Total using Variable within FOR-LO OP?

I suspect I'm going about this in the wrong way.  Please help me.  If some
kind soul were to take special interest, I will gladly email an xml file to
accompany the included xsl.

I'm performing an outer for-loop for a report header and an inner for-loop
to display report details.  Within the inner loop, I'm calculating 4
variables (HOURLY, LESSER, SPECIALTY, SAVINGS) which successively evaluate
each other to get thier results, and eventually calcuate a GRANDTOTAL in
each inner for-loop.  (words in CAPS represent appropriate template names).

Then, I need to calculate the BATCHTOTAL based on the GRANDTOTAL variables
displayed in each inner for-loop.  

Essentially, it goes: <loop> - report header - <inner loop> - report details
- </inner loop> - series of subtotals based on report details (HOURLY,
LESSER, SPECIALTY, SAVINGS) - report total (GRANDTOTAL) </loop> - sum(report
totals) to accomodate multiple reports (BATCHTOTAL).

PROBLEM:  I can't figure out how to calculate the BATCHTOTAL.  I think it's
because with each loop, the GRANDTOTAL variable goes out of scope.

Thanks to anyone who will help.

Here is some xsl code to illustrate my efforts.  The templates of interest
include: HOURLY, LESSER, SPECIALTY, SAVINGS, BATCHTOTAL.
