Having issues with PHP and Wordpress

If anyone can help it would be appreciated.

I am wanting to run this script http://www.mm0zif.org.uk/wxastronomy.php which displays Space Weather. I’ve configured the pages as per the instructions, but when I run the page I get:

Warning: require_once(Settings.php) [function.require-once]: failed to open stream: No such file or directory in /home/marcus_mm0zif/mm0zif.org.uk/wxastronomy.php on line 30

Fatal error: require_once() [function.require]: Failed opening required ‘Settings.php’ (include_path=’.:/usr/local/lib/php:/usr/local/php5/lib/pear’) in /home/marcus_mm0zif/mm0zif.org.uk/wxastronomy.php on line 30

Now as I have no Settings.php file what do I need to make this map to the correct directory ?

Many thanks for your help
