I get the following error messages on my index.php page..

Warning: main(counter.php): failed to open stream: No such file or directory in /home/www/cnhiokmedia/tnt/slideshows/may3tornado/index.php on line 1

Warning: main(counter.php): failed to open stream: No such file or directory in /home/www/cnhiokmedia/tnt/slideshows/may3tornado/index.php on line 1

Warning: main(): Failed opening 'counter.php' for inclusion (include_path='.:/usr/local/lib/php') in /home/www/cnhiokmedia/tnt/slideshows/may3tornado/index.php on line 1

What am I doing wrong?

your missing the counter.php file or you have not set the propa location to where the file is located, you always get that same error for same reasons I just stated.
