Yes, it might be easier to always assume that the parameter values from
the CGI program is a list, if you're reading from that multiple-value
selectbox.


The CGI documentation at:

    http://www.python.org/doc/lib/node404.html

talks about a high-level function called getlist() that should be useful.
It should return a list --- even a list of one element --- so that your
processing of that data should be uniform.


Hope this helps!
