Trying a successful entry in the table will become a possibility only when you
enter a unique key, in other words, a CurrencyCode that doesn't exist. To
access the form again, click OK in the Exception dialog. Modify the Currency
Code USD to US (I know this is not a real currency code, but for the sake of our
example, it's worth trying), and click Insert Currency button. You will see a
successful insertion, as shown in Figure 13-10.
