Static Function problem

Question

Hi, I have been recently working on a program and have come across this error that has stumped me!
prefsPane.java:101: non-static method updateVar(int) cannot be referenced from a static context
divLetter = divPane.updateVar(0);
^
prefsPane.java:102: non-static method updateVar(int) cannot be referenced from a static context
divName = divPane.updateVar(1);
^
// divPane.java Creates a new divPane. DuH!
import java.awt.*;
import javax.swing.*;
import java.io.*;
import java.util.*;
public class divPane extends JPanel {
protected JLabel letterLabel, nameLabel;
protected JButton applyButton;
String newLetter, newName;
public JTextField letterField, nameField;
     public divPane(String divName, String divLetter) {
          super(new GridBagLayout() );
          // Initalize the JLabels
          letterLabel = new JLabel("Id for Letters: ");
          nameLabel   = new JLabel("Id for Names: ");
          // Initalize the JTextField
          letterField = new JTextField(divLetter, 10);
          nameField   = new JTextField(divName, 10);
          // Add the Constraints for the Panel
          GridBagConstraints c = new GridBagConstraints();
          c.insets = new Insets(15,10,0,0);
          c.gridx   =  0;
          c.gridy   =  0;
          add(letterLabel, c);
          c.insets = new Insets(15,10,0,0);
          c.gridx   =  1;
          c.gridy   =  0;
          add(letterField, c);
          c.insets = new Insets(15,10,0,0);
          c.gridx   =  0;
          c.gridy   =  1;
          add(nameLabel, c);
          c.insets = new Insets(15,10,0,0);
          c.gridx   =  1;
          c.gridy   =  1;
          add(nameField, c);
     }// End Main Constructor          
     public String updateVar(int index) {
       if(index == 0)
         return (String)letterField.getText();
       else if(index == 1)
         return (String)nameField.getText();
       else
          System.out.println("Error!");
         return "Error!";
     }// End updateVar
}Here is the snippet of code that calls updateVar
public void doSave()
      JFrame nullframe = new JFrame();
         divLetter = divPane.updateVar(0);
         divName   = divPane.updateVar(1);
         System.out.println(divName);
         System.out.println(divLetter);
}Note: This is a problem from one of my previous posts. (http://forum.java.sun.com/thread.jsp?forum=31&thread=551160&start=15&range=15&hilite=false&q=)

Thank you, how might I reference that function without
making it static.You haven't said if doSave is in the same class or not. If it's in the same class then you are able to call it without another object.
divLetter = updateVar(0);Look at the other posts if you want to know to to access it from another object.
