XI and XSLT

Question

hi.. I have a XLST using 'for-each-group'.
When I use Altova XMLSpy, my XLST works fine, but when I import it to XI, it executes successfully, but it has no output.
Does anyone know why?
I can't figure out why it doesn't work in XI. Am I missing anything?
It works fine in XMLSpy.
