Creating Dynamic Forms Page 6




This page takes each component of the the new_tran2.asp page and
inserts it into the components table. The trick is traversing the
request collection since the number of request items can be
different for any transaction. Also the submit and reset buttons are
part of the collection sent to this page, so we must make sure we
have logic to handle or else they will be inserted into the
database.
