I made a couple of changes and it gets as far as the
database queries before bombing out...

fp=open("/var/www/html/sf/frame.html", "r")
->
fp=open("trial1.html", "r")


    print"""<FORM METHOD="POST" ACTION="/cgi-bin/sf/trial1.py">
->
    print"""<FORM METHOD="POST" ACTION="trial1.py">


Just to make it point at the right places...

How are you calling the script?
(in other words, should you be calling trial1.py and
not trying to load -- or force python to process -- trial1.html ?)

The error message you are getting looks more like a problem
with the server being misconfigured ...

Try to get the most basic script running first ("hello world")
before you start adding in other things.


I used a twisted webserver to run the script ...


pwd
/usr/home/lee/python/cgi

ls
acgi.rpy        trial1.html     trial1.py


cat acgi.rpy
from twisted.web import static, twcgi
class PyScript(twcgi.FilteredScript):
    filter = '/usr/local/bin/python'
resource = static.File("/home/lee/python/cgi/")
resource.processors = {".py": PyScript}


mktap web --port 9999 --path /usr/home/lee/python/cgi
twistd -f web.tap


Then I accessed it as:
http://localhost:9999/acgi.rpy/trial1.py
