    Default Cannot find symbol - variable mText

    Hey all i have been writing some code, it allows a user to select a file, a txt file, it then reads the contents of the file and then sends the contents to a printer this case a hp 8600, but on compling i get an error, Cannot find symbol - variable mText, why is this, it should be retriving mText from above as this now should contain all the data from the txt file, what am i doing wrong ?


    code:

    Java Code:
    import java.awt.*;
    import java.awt.font.*;
    import java.awt.geom.*;
    import java.awt.print.*;
    import java.text.*;
    import java.io.*;
    import javax.swing.*;
    
    public class PrintText implements Printable {
    
    
        // Below the code will allow the user to select a file and then print out the contents of the file
        public static void main(String[] args) throws IOException {
    
            //selects the file
            JFileChooser chooser = new JFileChooser();
            chooser.showOpenDialog(null);
            File file = chooser.getSelectedFile();
            String filename = file.getName();
            //System.out.println("You have selected: " + filename);  testing to see if file seleected was right
            String path = file.getAbsolutePath();
    
            //Reads contents of file into terminal 
            //FileReader fr = new FileReader("filename");
            // FileReader fr = new FileReader("D:/Documents/" + "filename")); 
    
            FileReader fr = new FileReader(path); 
            BufferedReader br = new BufferedReader(fr); 
            String mText; 
            while((mText = br.readLine()) != null) { 
                //Displays the contents of the file in terminal
                System.out.println(mText); 
            } 
            //fr.close(); 
        } 
    
    
            //private static final String mText = 
            //    "This is a test to see if this text will be printed "; //This works perfectly fine

    Make sure you let the folks at SO - and anywhere else you may have included in the discussion about this - that the problem is solved. (Or this aspect of it at least).
