I somehow can't find problems with a few lines
// The quarterStats-program should be able to let the user
// enter four sales-figures for 6 divisions of a company.
// (For 4 quarters in a stock-market year.)
// FOR HELP NEEDED, I SELECTED THE LINES THAT HAVE
// SHOWN UP ERRONEOUS ON THE COMPILER.
// Use this Scanner-class import-statement for input and output.
import java.util.Scanner;
// Use this DecimalFormat-class import-statement for numerical-setups.

// the sales-figure array that will hold all of the figures,
double[][] salesFigures = new double[QUARTERS][DIVISIONS];
// the general-figure variable for each entry,
double figure,
// the variable for the highest sales-division for each quarter,
highestQuart = salesFigures[0][0],

avSales,
// the accumulator for the average,
