Hi Sarah,

Thanks for a prompt feedback.  I knew it will be very vague without
example.  However, I only used two commands to import data and had no
'apparent' errors.  The original data have about 19000 obs and I was able
to reduce about 3200.  I wonder if I can attach the data file (size:
109K) with my email.

Best,

Steve
