Why won't the textField print date?

Why wont this tidField.setText(date); work? Everything else works, the date is taken from getDatum() which is a diffrent class that works perfectly fine when called here textArea.append(r.getLista()); but for tidField.setText(date); it wont change the field

 final JComboBox<String> comboBox = new JComboBox<String>();
            comboBox.addItem("Företag");
            comboBox.addItem("Normal");
            comboBox.addItem("Student");
            comboBox.addActionListener(new ActionListener() {
                public void actionPerformed(ActionEvent event) {
                    Kund kek = new Kund();
                    int kb = 0;
                    String date = kek.getDatum();
                    String SaldoString = "";
                    JComboBox<?> comboBox = (JComboBox<?>) event.getSource();
                    Object selected = comboBox.getSelectedItem();
                     if(selected.toString().equals("Normal")) {
                            Register r = new Register();
                            Kund k = new Normal();
                            k.setBelopp(100);
                            k.setDatum(date);
                            r.regKund(k);
                            int tempbelopp = k.getBelopp();
                            String b = Integer.toString(tempbelopp);
                            tidField.setText(date);
                            beloppField.setText(b);
                            kb = kb + 100;
                            SaldoString = Integer.toString(kb);
                            saldoText.setText(SaldoString);
                            textArea.append(r.getLista()); 
                            }
                        else if(selected.toString().equals("Student")) {
                            Register r = new Register();
                            Kund k = new Normal();
                            k=new Student();
                            k.setBelopp(50);
                            k.setDatum(date);
                            beloppField.setText(date);
                            tidField.setText(date);
                            if( kb >=50)
                                r.regKund(k);
                                kb = kb - 50;

                                                    textArea.append("Det finns inga cash, student reggades ej!" + "\n");

                    }
                        else if(selected.toString().equals("Företag")) {
                            Register r = new Register();
