Problem with Listener/Event format

I am having a problem setting up the Listener/Event operations in this code.  I will admit the rest of the code is not complete but it will no longer build.

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.text.DecimalFormat;

public class SeeMort extends JFrame implements ActionListener
{
    JPanel row1 = new JPanel();    
    JLabel title = new JLabel("Mortgage Calculation Tool");    
    JPanel row2 = new JPanel();
    JLabel amt = new JLabel("Enter Loan Amount");
    JLabel blank1 = new JLabel("           ");
    JLabel term = new JLabel("Enter Term in Months");
    JLabel blank2 = new JLabel("           ");
    JLabel rate = new JLabel("Enter Percentage Rate");    
    JPanel row3 = new JPanel();
    TextField amtx= new TextField(8);
    TextField termx= new TextField(8);
    TextField ratex= new TextField(8);    
    JPanel row4 = new JPanel();
    Button calc = new Button("Calculate Payment");
    JPanel row5 = new JPanel();
    TextField answer= new TextField(14);
   
    public SeeMort()
    {
        super("Mortgage Calculator");
      setSize(550, 500);
      setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
      setVisible(true);
        GridLayout layout = new GridLayout(5, 5, 145, 45);
        Container pane = getContentPane();        
        pane.setLayout(layout);
        row2.add(title);
        row3.add(amt);
        row3.add(blank1);
        row3.add(term);
        row3.add(blank2);
        row3.add(rate);
        pane.add(row2);
        row4.add(amtx);
        row4.add(termx);
        row4.add(ratex);
        pane.add(row3);
        pane.add(row4);        
      pane.add(calc);
        calc.addActionListener.(this);
        row5.add(answer);
        pane.add(row5);
        setContentPane(pane);
    }
   
    public void actionPerformed(ActionEvent ev)
    {
        if(ev.getSource() == calc);
        {
            int amount = Integer.parseInt(amtx.getText());                        //init var for loan amt
            int term = Integer.parseInt(termx.getText());                              //init var for length of loan
            double pmt = 0;                             //init var for payment
            double rate = Double.parseDouble(ratex.getText());                        //init var for interest rate
            {
                rate = (rate/12);                       //divide annual rate to get monthly rate
                term = (term * 12);                     //multiply years to get length in months
                pmt= (amount * (rate)) / (1-Math.pow(1 + rate, - term));    //compute payment
            }
            java.text.DecimalFormat dec = new java.text.DecimalFormat(",###.00");               //format next output to dollars.cents
            answer.setText(pmt.getText);               //display payment
        }
    }
    public static void main(String[] args)
    {
        SeeMort frame = new SeeMort();
    }
}

This line:
calc.addActionListener.(this);
is saying "expected identifier" even though I think I have assigned one.

This line:
answer.setText(pmt.getText);
is saying double cannot be dereferenced.

Sorry for the format but I couldn't figure out how to add code tags to my post.
I appreciate any help.
Thanx,
Dan
