[XSL-LIST Mailing List Archive Home] [By Thread] [By Date] [Recent Entries] [Reply To This Message] XSLT: SUM function Not working.
 I know this is weak code (I am just learning), but I can not get my XSLT to
compute the Average Price of the /Quotes/Quote, for each Symbol.
See Desired Output (include) Average now = 0. It does not seem to be
seeing the Param telling it which $CurrentSymbol we are now working with in
the loop.
The offending Template is the last one at the bottom of the XSLT. I added
some <!-- comments, at offending spot -->
Any help would be greatly appreciated.
Thanks in advance !!
