The National Commerce Bank has hired you to generate an application which verifies a customer personal identification number (PIN). A valid PIN refers to a seven-digit number which meets following specifications:

Digit 1: Must be in the range of 7 through 9.
Digit 2: Must be in the range of 5 through 7.
Digit 3: Must be in the range of 0 through 4.
Digit 4: Must be in the range of 0 through 9.
Digit 5: Must be in the range of 6 through 9.
Digit 6: Must be in the range of 3 through 6.
Digit 7: Must be in the range of 4 through 8.

The application must enable the user in order to enter the seven digits on a form. When user enters a digit which does not fall into acceptable range, an error message must be displayed once the verify button is clicked. If all seven digits entered fall into acceptable range, a message must be displayed telling the user that he has successfully entered a valid pin number.
