Good catch, sorry about that. I noticed you had spaces in the "how many" 
field in your form. Did your cgi still work? If not, I guess you figured 
that out by now too.

Interestingly, I had trouble getting the server/cgi to work with python 
2.4/Windows XP.

If I started the server with python 2.4 and put 2.4 in the cgi's #! 
line, the cgi didn't work.

If I used 2.3 to start the server, and put 2.3 or 2.4 in the cgi's #! 
line, the cgi worked.

I tried the same combinations on linux, and they all worked fine.

Anyone else seen this problem with python 2.4 on windows xp? I looked 
quickly at diffs of the relevant codes between 2.3 and 2.4, and I did a 
quick bug search on sourceforge, but didn't turn up anything yet.

Of course it may not be a bug; it may be a problem with my setup. The 
files I used are posted below, in case anyone wants to try to reproduce 
the result I saw.

Thanks.
