I don't know what you server path will be - only you or your host would know. I cannot tell by visiting your site unless you have an error message.

You could upload searchresults.php file unconfigured and see if it generates any error messages. If so, it may be possible that it could show you your server path within that error message (but remember in the case used in the script, you need to add the / on the end if it is not there like in the example.
