I've got a problem with using the XPATH functions. When I try to call some functions like lower-case or upper-case etc,they are not executed and I can't figure the problem out. I included the namespace xmlns:fn="http://www.w3.org/2005/xpath-functions" at the top of my XSL stylesheet and use fn namespace to call these functions but anyway nothing is working. Can anyone explain the reason and what I should do in order to be able to use the following functions?

Cheers
