Apache and PHP

I installed apache and PHP on my Windows2000 professional machine.Trying to configure Apache for Php. I typed the following lines at httpd.conf file
Script Alias /php4/ "c:/php/"
Action Application /x-httpd-php4 "/php4/php.exe"
Add Type application /x-httpd-php4.php

After typing above line, when i restarted my apache server i got the error " Could not start apache services on local computer
The service did not return an error. This could be a internal windows error or an internal service error.

Can any body tell me what am i doing wrong?

Aprreciate it

re-read installation notes, you've mis-written every single line.
