Apps problems adding a RadioGroup in Mark L. Murphy's android tutorial

[Mikhail617]

I'm going through the "A Fancier Form" chapter in Mark L. Murphy's "Android Tutorials" book (1st edition) and I can't get past step#2: Add a RadioGroup. The application compiles and installs on emulator and phone with no errors but when I try to run it I get the:

Sorry!
The application LunchList
(process apt.tutorial) has
stopped unexpectedly. Please try
again.

This is the code from the book (the only code that changes in that section is the RadioGroup part):

<?xml version="1.0" encoding="utf-8"?>
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:stretchColumns="1"
>
<TableRow>
<TextView android:text="Name:" />
<EditText android:id="@+id/name" />
</TableRow>
<TableRow>
<TextView android:text="Address:" />
<EditText android:id="@+id/addr" />
</TableRow>
<TableRow>
<TextView android:text="Type:" />
<RadioGroup android:id="@+id/types">
<RadioButton android:id="@+id/take_out"
android:text="Take-Out"
/>
<RadioButton android:id="@+id/sit_down"
android:text="Sit-Down"
/>
<RadioButton android:id="@+id/delivery"
android:text="Delivery"
/>
</RadioGroup>
</TableRow>
<Button android:id="@+id/save"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Save"
/>
</TableLayout>

Any ideas anyone???

Thanks,
