RE: for-each loops : calculations outside the loop, using data from insi

My advice is to use a recursive template.  Take a look at this for help on
recursion if you need it:

http://www-106.ibm.com/developerworks/xml/library/x-xslrecur/

Also, not sure if it applies, but make sure you account for a StartTime of
2200 and an end time of 0400.  This would give you -1800.  In this case, add
2400 to 0400 and then subtract the 2200 = 600.

Subject: [xsl] for-each loops : calculations outside the loop, using data
from inside

I'm sure this will be simple for a more experienced xsl coder. I've removed
the bulk of my code, leaving only the relevant parts.  (removed code
designated by --- )

I want to add a number from each "for-each" run-thru, to a total that will
be displayed once the loop has completed. Can't find the solution anywhere! 
See comments in code below! 

Cheers :)
