The support guy looked at it and gave me this:

He says I have a syntax error, though I'm b*ed if I can see where it
could be. Can anyone here suggest anything?


Oh lordy lordy lordy, you've got one fine example of incompetence in
action.

From the support forum:

The "administrator" John is trying to execute a Python script with Perl.
I notice that you pointed that out to him, and his response was:

Sorry for delay. if we try to run this script by python we will get same
error.

python -t python1.cgi
Content-type: text/html

Traceback (most recent call last):
File "python1.cgi", line 6, in ?
print form["essay"].value
File "/usr/local/lib/python2.4/cgi.py", line 559, in __getitem__
raise KeyError, key
KeyError: 'essay'

we can test perl or cgi scripts using perl command.

PLease fix syntax error so it will work fine.

It is NOT the same error. There are NO syntax errors in the script, there
is a runtime error. The so-called administrator is wrong: you can't use
Perl to test just any old CGI scripts. They have to be written in Perl.


I see from the source code on your page that you have a line:

<TEXTAREA NAME="essay" COLS=60 ROWS=20 WRAP=HARD></TEXTAREA>

You have two lines in your cgi script:

form = cgi.FieldStorage()
print form["essay"].value

Having never done cgi programming, I'm not sure what the problem is, but
after reading help(cgi) I'll take a stab in the dark and say try this:

print form.value

It might also help for you to try this:

print form.keys()


Good luck with the "admins" at your hosting company.
