Local variable accessed within inner class

Question

Hey everybody,
My program keeps telling me that it wont work because one of my methods is calling a local variable inside an inner class. Does anyone know what this means and how to fix it?
Heres the code:
public class SliderExample extends JPanel{
int value=0;
public SliderExample(int imw, int imh, Image img, BufferedImage buf, Graphics2D biCon){
super(true);
this.setLayout(new BorderLayout());
JSlider slider= new JSlider(JSlider.HORIZONTAL,0,imw,25);
slider.setMinorTickSpacing(10);
slider.setMajorTickSpacing(100);
slider.setPaintTicks(true);
slider.setPaintLabels(true);
JButton redraw= new JButton("Scroll");
redraw.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent ev){
reDraw(slider,img,buf,biCon,imw,imh);
add(slider,BorderLayout.CENTER);
add(redraw,BorderLayout.AFTER_LINE_ENDS);
public void reDraw(JSlider slid, Image im, BufferedImage bf, Graphics2D biC, int iw, int ih){
value=slid.getValue();
Graphics g= getGraphics();
g.drawImage(im,value,0,iw,ih,this);
g.drawImage(bf,value,0,iw,ih,this);
biC.drawImage(bf,value,0,iw,ih,this);
Any ideas???
THanks,

Its getting them from another class thats calling the mothod to construct the slider bar with dedraw button. Thats a pretty big class but I will post the code where I called the method:
public class Process extends JFrame implements MouseListener, MouseMotionListener{
private int [][] points;
private int [] lengths={0};
private int [] bin;
private String imstr;
private String imsav;
private int imgw=658;
private int imgh=512;
private int xArrayPos=0;
private int yArrayPos=0;
private int xpos=0;
private int ypos=0;
private int xprev;
private int yprev;
private int xadd;
private int yadd;
private String filstr;
Image image;
SimpleGUI gui;
BufferedImage buffer;
Graphics2D biContext;
Graphics2D g2;
BufferedImage last;
Graphics2D lastContext;
public Process(){
JFrame slideFrame = new JFrame("Please slide to scroll image");
slideFrame.setContentPane(new SliderExample(imgw, imgh,image,buffer,biContext));
slideFrame.pack();
slideFrame.setVisible(true);
Thats what anything having to do with that function in the other class that calls the Slider Class.
Do you know how I can fix this??
Thanks,
