arrays....

How do you make array's global? I have buttons, ints, etc being able to be read and manipulated from within an actionPerformed but when I declare and create a new instance of it within main class I cannot seem to use it within my action button routine. IE:

public class B2C5 extends JFrame implements ActionListener
{
     String Catalog[][];
     Action retaction;
      public B2C5()
      {
           Catalog = new String[7][5];
           String Catalog[][]={{"DR800","Drills - Corded","3/8 Variable","139.99","Yes"},
                {"DR700","Drills - Corded","3.2 amp","50.00","Yes"},
                {"CS600","Circular Saw","18 volt","199.99","Yes"},
                {"CS500","Circular Saw","14 volt","99.99","No"},
                {"SD200","Sander","Palm","29.99","Yes"},
                {"SD300","Sander","Orbital","59.95","Yes"},
              {"GR200","Grinder","Rotary","89.95","No"}};
           retaction=new RETAction();
      }
      class RETAction extends AbstractAction
      {
           public RETAction()
           {
                super("Retail Customer", new ImageIcon("retail.png"));
          }
           public void actionPerformed (ActionEvent e)
           {
                //set textfields with array data
                Item1.setText(Catalog[0][1] + " " + Catalog[0][2] + " " + Catalog [0][3]);
                Item2.setText(Catalog[1][1] + " " + Catalog[1][2] + " " + Catalog [1][3]);
           }
      }
}

Every time I click on the retail button I get nulls in my text fields. But if I put the array in the actionPerformed area it works.
