21. In this exercise, you modify one of the Projected Sales applications from this lesson.

Use Windows to make a copy of the Sales Solution folder. Rename the copy Sales Solution-Intermediate. Open the Sales Solution (Sales Solution.sln) file contained in the Sales Solution-Intermediate folder. Rather than using $150,000 as the sales goal, the user should be able to enter any sales goal. Modify the interface and code as needed, and then test the application appropriately.
