Extension functions depend on which processor you are using, so that's the
first thing you should tell us.
It's also possible of course that you aren't using the processor you think

Hey Guys,
I am trying to create a pie chart in svg from a very simple
xml file. When I
try to create the file I get...
file:/C:/Documents and Settings/Chris/My
Documents/EyeStreet/Mockup/Rev2/XSL
Files/CreatePie.xslt; Line #54; Column #-1; XSLT Error

It seems to me that this is a problem with Java paths, but I
can't seem to
get it figured out. Any help would be appreciated.
Thanks
