I can't get it to work

// For handling the text views
// This is up in the top too --> DBAdapter db;
  public void createReservation(View view) {
        db.open();
        EditText nameText = (EditText)findViewById(R.id.nameText);
        String nameValue = nameText.getText().toString();
        EditText emailText = (EditText)findViewById(R.id.emailText);
        String emailValue = emailText.getText().toString();
        EditText phoneNumber = (EditText)findViewById(R.id.phoneNumber);
        String phoneValue = phoneNumber.getText().toString();
        EditText addressText = (EditText)findViewById(R.id.addressText);
        String addressValue = addressText.getText().toString();
        EditText zipNumber = (EditText)findViewById(R.id.zipNumber);
        String zipValue = zipNumber.getText().toString();
        EditText arrivalDate = (EditText)findViewById(R.id.arrivalDate);
        String arrivalValue = arrivalDate.getText().toString();
        EditText departureDate = (EditText)findViewById(R.id.departureDate);
        String departureValue = departureDate.getText().toString();
        EditText notesArea = (EditText)findViewById(R.id.notesText);
        String notesValue = notesArea.getText().toString();
        EditText roomNum = (EditText)findViewById(R.id.roomNum);
        String roomValue = roomNum.getText().toString();

        db.insertRow(nameValue, emailValue, phoneValue, addressValue, zipValue, arrivalValue, departureValue, roomValue, notesValue);
        Toast toast = Toast.makeText(getApplicationContext(), "Creating Reservation", Toast.LENGTH_LONG);
        toast.show();
        db.close();
    }


//Then this is my insert row from the DBAdapter

 public long insertRow(String nameValue, String emailValue, String phoneValue, String addressValue, String zipValue, String arrivalValue, String departureValue, String roomValue, String notesValue) {
        ContentValues initialValues = new ContentValues();

        initialValues.put(ZIP_COLUMN, zipValue);
        initialValues.put(ARRIVAL_COLUMN, arrivalValue);
        initialValues.put(DEPARTURE_COLUMN, departureValue);

        initialValues.put(NOTES_COLUMN, notesValue);

        // Insert the data into the database.
        return db.insert(DATABASE_TABLE, null, initialValues);
    }
