That's exactly what session scope is for. :-) Request scope means that the bean is gone at the end of the request (that is, when Verify.jsp finishes rendering). If you put it in session scope you'll be set. > Question #2: Is it possible to use two beans within a single > jsp page?

Absolutely! As long as they have different id attributes, you can use as many beans as you like. > Question #3: I include a button to give the option to go > back and make changes.

As long as the bean is in session scope, you'll be able to access it from any page the user accesses. -- Tim Moore / Blackboard Inc. / Software Engineer 1899 L Street, NW / 5th Floor / Washington, DC 20036 Phone 202-463-4860 ext. 258 / Fax 202-463-4863 -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]>
