Hey Nadya,
It's easy to miss things like this even for the best gurus like Ken (OK not Ken:) at times.
I posted a code on a Turkish site (yes now there is one - Fox4um:) and they said it was giving error. Can you believe code, my code was giving error :) I realized later at the very top I defined the sample data path which doesn't match theirs and didn't warn about it. Anyway we all know I make much bigger mistakes. Cool down :)
