Passwords in FrontPage

My friend is trying to put a password protection on his web page, but is having problems. He says he's already got the password entry screen done and he's set the properties for the password, but he doesn't know how to link that page (once the password has been entered) to the next page? Does anyone know how to do this? And then how to set it up so that he can get a 'wrong password' response page when needed. He's using Front page. Thanks in advance.
