Thanks John and Alan

I get the following error when I run the script from IDLE:

Traceback (most recent call last):
  File "C:\Cgi-bin\friends1.py", line 15, in <module>
    who = form['person'].value
  File "C:\Python25\lib\cgi.py", line 567, in __getitem__
    raise KeyError, key
KeyError: 'person'

Windows XP, python 2.5
