Thanks Ryan. Do you have any suggestions on how to get an alert if the
file doesn't exist ? It only gives me "no files checked" when the file
isn't there. That's okay if I can get that translated into an email that
informs someone that no file was created.
Does that make sense, or is my logic flawed ?
