Button To Display An Image

I have an assignment that is due tomorrow that I am struggling with. I want to be able to click the next button in this applet, and then repaint all the graphics. Board contains an array with all of the chess pieces on a board, and when the button is clicked I want to be able to get the next move, but for now I just wanted to call a function to move one piece just so I know it's working. Here is my applet code, I could post all the other files, but I am almost positive they all work correctly, and I am just having trouble with the applet.

Code:

import java.awt.*; public class Test extends java.applet.Applet{    Button nextButton;    Image board, bp, wp, bn, wn, br, wr, bb, wb, bk, wk, bq, wq;    Board currentBoard = new Board();    public void init() {     	board = getImage(getCodeBase(), "../images/board.jpg");  bp = getImage(getCodeBase(), "../images/bp.gif");  wp = getImage(getCodeBase(), "../images/wp.gif");  bn = getImage(getCodeBase(), "../images/bn.gif");  wn = getImage(getCodeBase(), "../images/wn.gif");  br = getImage(getCodeBase(), "../images/br.gif");  wr = getImage(getCodeBase(), "../images/wr.gif");	  bb = getImage(getCodeBase(), "../images/bb.gif");  wb = getImage(getCodeBase(), "../images/wb.gif");  bk = getImage(getCodeBase(), "../images/bk.gif");  wk = getImage(getCodeBase(), "../images/wk.gif");  bq = getImage(getCodeBase(), "../images/bq.gif");  wq = getImage(getCodeBase(), "../images/wq.gif");    	nextButton = new Button("Next");        add(nextButton);    }    public boolean action(Event evt, Object arg) {        if (evt.target instanceof Button) {            getMove((Button) evt.target);            return true;        } else {            return false;        }    }    void getMove(Button b) {        changeBoard();        repaint();    }        public void paint(Graphics screen) {  //	Draw Board  screen.drawImage(board, 0, 50, 900, 930, this);  String hi = "hi";  for(int y = 1; y < 9; y++)  {  	  	char tempX = 'a';  	for(int x = 1; x < 9; x++)  	{    if(currentBoard.colorOn(tempX, y) != 'n')    {    	if(currentBoard.colorOn(tempX, y) == 'b')    	{      if (currentBoard.typeOn(tempX, y) == "Pawn")      {      	screen.drawImage(bp, convertX(tempX), convertY(y), 100, 100, this);      }      if (currentBoard.typeOn(tempX, y) == "Rook")      {      	screen.drawImage(br, convertX(tempX), convertY(y), 100, 100, this);      }      if (currentBoard.typeOn(tempX, y) == "Knight")      {      	screen.drawImage(bn, convertX(tempX), convertY(y), 100, 100, this);      }      if (currentBoard.typeOn(tempX, y) == "Bishop")      {      	screen.drawImage(bb, convertX(tempX), convertY(y), 100, 100, this);      }      if (currentBoard.typeOn(tempX, y) == "King")      {      	screen.drawImage(bk, convertX(tempX), convertY(y), 100, 100, this);      }      if (currentBoard.typeOn(tempX, y) == "Queen")      {      	screen.drawImage(bq, convertX(tempX), convertY(y), 100, 100, this);      }    	}    	if(currentBoard.colorOn(tempX, y) == 'w')    	{      if (currentBoard.typeOn(tempX, y) == "Pawn")      {      	screen.drawImage(wp, convertX(tempX), convertY(y), 100, 100, this);      }      if (currentBoard.typeOn(tempX, y) == "Rook")      {      	screen.drawImage(wr, convertX(tempX), convertY(y), 100, 100, this);      }      if (currentBoard.typeOn(tempX, y) == "Knight")      {      	screen.drawImage(wn, convertX(tempX), convertY(y), 100, 100, this);      }      if (currentBoard.typeOn(tempX, y) == "Bishop")      {      	screen.drawImage(wb, convertX(tempX), convertY(y), 100, 100, this);      }      if (currentBoard.typeOn(tempX, y) == "King")      {      	screen.drawImage(wk, convertX(tempX), convertY(y), 100, 100, this);      }      if (currentBoard.typeOn(tempX, y) == "Queen")      {      	screen.drawImage(wq, convertX(tempX), convertY(y), 100, 100, this);      }          	}    }    tempX++;  	}  }	}	public int convertX(char a) {  return ((a-97)*(100)) + 90;	}		public int convertY(int a) {  return ((a-1)*(100)) + 90;	}	public void changeBoard(){  currentBoard.move('b',2,'b',3);  currentBoard.move('b',7,'b',5);	}}

I suppose your assignment is passed by now, and I hope you found an answer to your question. I would be interested in the chess game if you could send me the projects files. I'm just starting to learn java myself,and this probally has not a thing to do with your question, but I was noticing that the applet source code only contains one import statment that doesnt seem right.
