If a checkbox is set, you'll get a request parameter value for it. If it is not checked, you will not get a request parameter value for it. That's how it works. Your code which reads the request parameter values has to understand that. If you don't see the parameter, the box wasn't checked. =========================================================================== To unsubscribe: mailto [EMAIL PROTECTED] with body: "signoff JSP-INTEREST".
