Does $firstN have a value in the PartyList/When [1] template? Is the PartyList/When [last()] template actually being called? 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. Incidentally, the match="PartyList/When[last()]" is potentially very expensive (though it all depends on the optimizer), and not really necessary here. I would do all the work in one template myself.
