Q:

textPane cannot be resolved

I am writing a program in eclipse that generates reports based on inputs from a user. I have a JTextPane in a JScrollPane to allow the user to enter a description of the text, then add it to the system by pressing a button, but I am getting the error "textPaneDescription cannot be resolved". 
The code(excluding imports)
public class GUI{

private JFrame frame;

private JTextField textFieldDays;
private JTextField textFieldSmallTools;
private JTextField textFieldHireCharges;
private JTextField textFieldMaterials;
private JTextField textFieldSubContracted;
private JTextField textFieldSupplyOnlyWorks;
private JTextField textFieldConsultants;
private int counter = 0;

}

A:

It looks like you are accessing the variable textPaneDescription before you actually declared it.
You access the textPaneDescription when adding an action listener.
tierOneArray.add(new Operative(textPaneDescription.getText() ... );
While not only till later in the code you declare the variable, thus it can not be resolved.
