Dear David,
Thanks for your help. I have left my project behind for 3 weeks because I
have to attend 2-week course in Italy and 1-week course in England. Today I
try to catch up where I left. Now, I have tried what you told me three weeks
ago... however I am not sure what exactly you mean about "verify the file
routine..." (see in the following attached message). Please help. Thank you
very much. Wish you all the best.
Best regards,
