Many thanks for your reply. I was simply under the impression that
'import urllib2' would take care of the namespace issue and simply
import everything in urlib2, making it unnecessary to have to
reference HTTPError and URLError.  Sorry for being dense about this
(I'm very new to Python).. Again, thanks for your help.
