Hi, my code has 2 problem,

1. It doesn't display the c/f ( carried forward)

The result after the Event: Interview 1 2 3 4 5 6 7 8 9 10 Brazil Russia Venezuella Australia Russia Brazil USA Japan Australia Venezuella South Korea British Columbia Thailand China Thailand British Columbia South Korea Japan USA 22.99 28.28 23.61 33.69 17.47 42.15 22.58 Starting Position For Event: SwimSuit Competition Country China 28.44 25.70 26.83 Name Name 1 Name 2 Name 3 Name 4 Name 5 Name 6 Name 7 Name 8 Name 9 Name 10 Age 21 29 21 21 28 23 21 27 20 20 c/f 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00
