You can't CHANGE :BookAuthor or :BuyDate in this situation
as you may change the selection results - especially is
AutoRefresh on Parameter Change is ON.

I would suggest that either you insert a record direct, or
alternatively change :BuyDate to :BuyXXX so that you can use
BuyDate as the field name. ( Same with :BookAuthor ) While
using the same name for Parameters is allowed, normal
practice is to make them different to prevent this sort of
conflict.
