v. 3.0.6 problem? [phpWizard's calendar]

I've made some changes on a calendar found at http://phpWizard.net/resources/phpMisc/ -but allthough it works perfectly at home (Win2000, PHP v.3.0.12) it doesn't seem to work at all after uploading it to the server which runs PHP v.3.0.6 (phpinfo can be found at http://scs.no/test.php3 ). I've gone back to phpWizard's original script and uploaded it here: http://voxra.com/calendar_original.php3 can you see any obvious reason why this doesn't work? (The only thing I've changed: "<?"becomes "<?php" just because that's the way I do it.) You can view the source code here: http://voxra.com/source.php3?page_url=calendar_original.php3 Any help appreciated, it's such a pretty little thing and I would like it to work, could it be the version of PHP that pair.com runs that causes the problem? TIA, Randi Andersen
