Any ideas why this is being ignored? Wow, I would be annoyed if I used your site, as it rules out perfectly valid email addresses of a format I'd be likely to provide to a web site. Clue 1: Far more characters are valid before the @ sign. Clue 2: The underscore (_) is not valid after the @ sign. Why randomly make up guesses about what a valid email address might be? RFC 822 is no secret, and there are secondary references under every virtual rock. As for your ereg problem itself, it's returning true on a so-called valid address, so you'd be getting the opposite results of what you expect. Switch your if around or add a ! before the eregi call. miguel
