Getting Javascript variable into PHP

Has anyone had to get a javascript variable into your PHP script? I'm trying to have a javascript popup box come up whenever a user clicks to revoke a user's privilege. How do I know what was clicked on the javascript box in order to know whether to revoke the user's privilege or not? If there's a better way to do this please let me know. Thanks in advance for any replies. -- Michael Champagne, Software Engineer Capital Institutional Services, Inc. wk: mchampagne@capis.com hm: mchamp@texas.net ****************************************************************** This communication is for informational purposes only.
