Crontab PHP Script

Hi, Can someone please give me some guidance. I'd like to run a php script every minute (in reality every night, but just testing). I've done some reading and found that a crontab is the best way to go (I think). I'm using Plesk 7 on a Linux box and I have root access. I made a quick php script called crontab.php to email me. ============================================================== <?php //send email on domain /* subject */ $str_subject = "crontab test"; /* message */ $messagecontent = "this is a test to see if crontab working nightly\n\n"; /* to */ $to = "ryan@triomfgroup.com"; /* from */ $headers .= "From: tgWedding <development@triomfgroup.com>\r\n"; /* bcc */ // $headers .= "Bcc: development@triomfgroup.com\r\n"; mail($to, $str_subject, $messagecontent, $headers); ?> Then I setup my crontab command as: /home/httpd/vhosts/tgwedding.com/httpdocs/tgwedding/crontab.php <https://217.160.251.56:8443/sysuser/crontab_edit.php?cte_src=CTEJKgkqCSoJKg kvaG9tZS9odHRwZC92aG9zdHMvdGd3ZWRkaW5nLmNvbS9odHRwZG9jcy90Z3dlZGRpbmcvY3Jvbn RhYi5waHA=> I used " * " for every field except M, which I set to " 01 " to run every minute. It's not working...can someone guide me along and let me know what I've done wrong. Thanks, Ryan
