Call PHP file help

[betts02]

I have a php code for a slide show

PHP Code:

<?php// START of "Frontpage Slideshow" settings
    $nameOfSlideshowToDisplay = "myslideshow";                     // Enter the name of your slideshow. Slideshows are in folders inside /fpss/slideshows/.
    $URLofyoursite = "http://www.nextgenerationgamers.co.uk/forums";                     // Enter your site's URL.
    $AbsoluteServerPathofyoursite = "/home/nextgen6/public_html/forums";    // Enter the root path of your site on the server.
    
    // do not edit below this line
    include_once($AbsoluteServerPathofyoursite."/fpss/mod_fpslideshow.php");
// END of "Frontpage Slideshow" settings
?>

I have all the files uploaded to the correct place
