Notes to Graders:
You should run the application from the contestant’s flash drive to verify the correct
execution.
Labels and boxes should be aligned.
Contestant Number must appear in code and on the bottom right side of the form at
time of execution
Tabbing between fields will be in logical order.
Results must not be hard-coded into the program.

CODING MAY NOT BE IDENTICAL TO SAMPLE.
