Thank you! I tried both, and the first works well. However, changing the
height_field call as you suggest gives me a 'File type not supported here'
error. I can now do what I was trying to do, but I'm curious about the error.
Could someone explain it to me? I find that I work better if I understand the
'why's behind then 'what's in a new program.Perhaps 'sys' isn't the correct
file-type?
