Hi Andy again, I have found that stupid thing. And it is magic end of line :)) Why it was not taken the particular line with supervisor is because the string "supervisor" in if statement had additional blank characters and I didn't see that. Maybe it would be good to demark the statement in brackets to beware of it. Sorry to spam you and thanks for help Pavel Pavel Jakl wrote: > Hi Andy, > > I re-produced it again.
