I have tried Exercise 17 several times and, each time, when I get to Step 21, I
do exactly as the instruction states: I select the Login component in the
Outline panel.

Step 22 refers to a "highlighted component" on the stage but I don't see any.
A couple of times, I saw handles and clicked within the component and deleted
it, as instructed.

When I return to the source view on Step 23, the Login component is still
there so I'm not sure what Step 22 was meant for in the first place.

In any case, I proceed and, when I get to Step 32, I run the application. But
clicking the Submit button does not switch to the reservation view.

Any ideas anyone?

Thanks!
