Code at line 38

booking[column][row] = name;//put name into chosen index

String  booking [][]= new  String [30] [6] ;//two dimensional array
System.out.println("Enter the seat column you want");//column entry
			char column=Keyboard.readChar();
System.out.println("Enter the seat row you want");//row entry
			int row=Keyboard.readInt();
System.out.println("Enter your name");//name entry
			String name=Keyboard.readString();

column and row are values that are entered by the user
column is defined as char because the user must selected a either A,B,C,D,E,F,
AND THEN select a seat number associated with that row any number 1 to 30

--- Update ---

then the name should fill in to the appropriate position in the array booking to the row and column the user entered

THanks for the help much appreciated lad
