[mod_python] help

 under windows 98 apache 1.3.17

I copy mod_python.dll to /apache/modules

copy mod_python to c:\python20\lib

add row LoadModule python_module modules/mod_python.dll to httpd.conf

add 

<Directory "C:/Apache/htdocs/python">
    AddHandler python-program .py
    PythonHandler mptest
    PythonDebug On
</Directory>

to httpd.conf too.

then restart apache. when i enter http://localhost/python, i can see mptest.py.

but when i click mptest.py, the browser tells me
