Hi. I'm trying to install and get the error message

Warning: Unable to access ../include/functions.php in /home/hsphere/local/home/photogallery/admin/install.php on line 459

Warning: Failed opening '../include/functions.php' for inclusion (include_path='.:/usr/local/lib/php') in /home/hsphere/local/home/photogallery/admin/install.php on line 459

any ideas what I should do? Thanks!
