I've had this 2D array problem for ages and would apprecoate any help :)

Question

I've posted a few times about this in the past and with your guys help I have gradually advanced.
Basically, all I want to do at the moment is fill the lowest position a counter can go in in a game of Connect Four.
The first counter goes to the bottom, then if you place another counter in the same column it goes above the previous counter you put in that same column and so on...
I have set up my 2D array and initialised integers for each player so when a counter is red the player = 1 and when yellow player = 2.
Here is my code...
CircleGrid [][] cArray = new CircleGrid[col][row]; //Declare array
static final int row = 6;
static final int col = 7;
for (int i = 0; i < col; i++)
                    for (int h = 0; h < row; h++)
                         cArray[i][h] = new CircleGrid();
                         gameCenter.add(new CircleGrid());
               JOptionPane.showConfirmDialog(game, "Welcome to Frenzy Fours. Press 'OK to begin or 'Cancel' to go back.", "Game", JOptionPane.OK_CANCEL_OPTION);
               /*if (cArray[col-1][row] && cArray[col-2][row] == 1) //This doesn't work at all...array out of bounds !?
                    System.out.println("testing");
public class CircleGrid extends JPanel implements MouseListener, MouseMotionListener
         int ifRed;
         int notIfRed;
             boolean ifEmpty;
          String currentColour = "White";
          final int empty = 0;
          final int competitorOne = 1;
          final int competitorTwo = 2;
             public CircleGrid()
               ifRed = 1;
               notIfRed = 0;
               int redCircles = 0;
               int yellowCircles = 0;
               ifEmpty = true;
               addMouseListener(this);
             public void alternateColour()
               ifEmpty = !ifEmpty;
               repaint(); //Repaint upon changes
             public void paintComponent(Graphics g)
             if (ifEmpty)
               g.setColor(Color.WHITE); //Set all of the ovals to white
         else if (ifRed == clicks)
               position--;
               addMouseListener(this);
                g.setColor(Color.RED); //Paint red
                currentColour = "Red";
                System.out.println(getColour());
                System.out.println(playerOneMove());
          else if (notIfRed == clicks)
               addMouseListener(this);
               g.setColor(Color.YELLOW); //Paint yellow
               currentColour = "Yellow";
               System.out.println(getColour());
               System.out.println(playerTwoMove());
               g.fillOval(5, 10, 42, 42); //Draw and fill oval
             public String getColour()
               return currentColour;
          public int playerOneMove()
               return competitorOne;
          public int playerTwoMove()
               return competitorTwo;
             public void mousePressed(MouseEvent ev)
               alternateColour(); //Use commands from this method
               if (clicks == 0)
                    clicks = 1;
                    repaint(); //Paint oval red
                    number--; //Decrement number of counters left by 1
                     counterNo1.setText(number + " counters left.");
                     move++;
                     moveCount1.setText(move + " moves.");
               else if (clicks > 0)
                    clicks = 0;
                    repaint(); //Paint oval yellow
                    number2--;
                     counterNo2.setText(number2 + " counters left.");
                    move2++;
                     moveCount2.setText(move2 + " moves.");
             }I think that is all of the code which matters for this!
I didn't choose to do this project and it is really stressing me out! If anybody could give me a nudge in the right direction (in really simple steps) that would be awesome. I appreciate you guys do this voluntarily (and for some even work) so I would be deeply grateful for any assistance in this matter.
Thank you. :)

}new Circle - cannot find symbol
gameCenter.add - cannot find symbol
Circle has been declared so I don't know why this is happening. :S
