Hi Michael
Does $firstN have a value in the PartyList/When [1] template?
yes.
Is the PartyList/When [last()] template actually being called?
yes.
If so, something very odd is going on. Tell us which processor you are
using, and post a complete stylesheet + source document so we can debug
it for you.
I am using MSXML not sure about the processor. If i have an xml
parser do i automatically have a processor aswell?
I am using xmlSpy to step through the transformation process. At
the bottom of this mail is the html output i am getting.
