redirecting to a new page

Hello again I have a page that takes info in from a form, and sends it to a php page. That page then checks if the info is valid or not. If its not it gives them the error, but if it is, then it adds the data to the database, and I would like it to then re-direct them to another page. The only things I could find to send people to a new page needed to be used in the header, which won't work. Any ideas? thanks Generic Player
