You are getting a "Page Expired" because the page you're trying to go back to was produced by a POSTed form. The browser won't rePOST data to the server unless the user explicitly allows it to (as a "security precaution"). If you want to redisplay form results without the Page Expired message, either (a) use GET in submitting the form, or (b) redirect to the display page after processing the POSTed form.
