[FieldTrip] variable "abort"

[paymando- morientes]

Dear all
I have a problem starting with field trip. When I call "ft_definevarible" function, it throws an error that "abort" variable is not defined. I checked the ".m file" for the function and it says that abort is set by "ft_preamble" function. So where is the problem? Should I change something in my script? or "ft_preamble" function is not doing its job?
by the way i hope I am sending this message to the right e-mail.

thanks in advance
payman
