Tabbed Application Crashes On Startup

I'm trying to make an Application to keep track of totals and Display them through a TextEdit contained in a Table. I would like to have several Tabs to keep track of different tables and therefore different totals. However when the application boots on an emulator it immediately stops working and crashes. Could anyone tell me what is wrong?

Android code:

public class CounterCounterActivity extends TabActivity implements OnClickListener {
/** Called when the activity is first created. */
TextView YourLife, OppLife;
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    TabHost tabHost=(TabHost)findViewById(R.id.tabHost);
    tabHost.setup();

    TabSpec spec1=tabHost.newTabSpec("Tab 1");
    spec1.setContent(R.id.tab1);
    spec1.setIndicator("Life");

    TabSpec spec2=tabHost.newTabSpec("Tab 2");
    spec2.setIndicator("+/-");
    spec2.setContent(R.id.tab2);

    TabSpec spec3=tabHost.newTabSpec("Tab 3");
    spec3.setIndicator("Poison");
    spec3.setContent(R.id.tab3);

    tabHost.addTab(spec1);
    tabHost.addTab(spec2);
    tabHost.addTab(spec3);
    tabHost.getTabWidget().getChildAt(0).getLayoutParams().height =50;
    tabHost.getTabWidget().getChildAt(1).getLayoutParams().height =50;
    tabHost.getTabWidget().getChildAt(2).getLayoutParams().height =50;
    ((Button) findViewById(R.id.button1)).setOnClickListener(this);
    ((Button) findViewById(R.id.button2)).setOnClickListener(this);
    ((Button) findViewById(R.id.button3)).setOnClickListener(this);
    ((Button) findViewById(R.id.button4)).setOnClickListener(this);
    ((Button) findViewById(R.id.button5)).setOnClickListener(this);
    ((Button) findViewById(R.id.button6)).setOnClickListener(this);
    ((Button) findViewById(R.id.button7)).setOnClickListener(this);
    ((Button) findViewById(R.id.button8)).setOnClickListener(this);
    YourLife=(TextView)findViewById(R.id.txt2);
    OppLife=(TextView)findViewById(R.id.txt1);
}
public void onClick(View view) {
    // TODO Auto-generated method stub
    @SuppressWarnings("unused")
    Intent intent = new Intent();
    int LY=20;
    int LO=20;
    int sel=0;

    {
        sel=0;
        if (view.getId()==R.id.button1)

        }
        if (view.getId()==R.id.button4)
        {
            sel=3;

        }
        if (view.getId()==R.id.button8)
        {
            sel=4;

        }
        if (view.getId()==R.id.button5)
        {
            sel=5;

        }if (view.getId()==R.id.button2)

Since you are extending a TabActivity in your Activity, you need to change the id of your TabHost in your XML.

<TabHost android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="@android:id/tabHost"
xmlns:android="http://schemas.android.com/apk/res/android"
>

Replacing

android:id="@+id/tabHost"

by

android:id="@android:id/tabHost"

should work.
