Two Dimensional Array Help

Im writting a program that makes the user enter in 4 quarter sales figures for 6 divisions of a company, using Joptionpanes. These results need to be stored in a two dimensional array. Then, using the JTest (settext, .append) functions i need to display the sales figures for each division, each divisions increase or decrease from the previous quarter, total sales for each quarter. The companies increase or decrease increase or decrease for each quarter. The average sales for all divsions that quarter, and the division with the highest figures for each quarter.

Thanks very much for the help in advance.

So what's the problem?
