External Log in page

I have been searching through the formuns for the external log in page. I am not understanding and it thus does not work. So far my errors are

Warning: main(init.php) [function.main]: failed to open stream: No such file or directory in /home/sherride/public_html/dougmacdonald/contact.php on line 13

Fatal error: main() [function.require]: Failed opening required 'init.php' (include_path='.:/usr/php4/lib/php') in /home/sherride/public_html/dougmacdonald/contact.php on line 13
