Error on inserting values to SQLite DB ?Can anyone solve this?

Below is the DB coding for creating Table Visitors to store name and adress of place

  public class DbFav {
 static final String DataBaseName = "Favdb";
 static final String favtable = "Visiters";

 static   final  String ColNam="Name";
 static   final  String ColAdd="Address";
    public static final int DATABASE_VERSION = 3;
  private static final String REGISTER_TABLE_CREATE ="Create table " +  favtable + "("+ColNam + " INTEGER PRIMARY KEY AUTOINCREMENT, " + ColAdd+ "    VARCHAR(15)) ";
private final Context context;
private DatabaseHelper DBHelper;
private SQLiteDatabase db;
public DbFav(Context ctx){
    this.context = ctx;
    DBHelper = new DatabaseHelper(context);
}
private static class DatabaseHelper extends SQLiteOpenHelper{
    public DatabaseHelper(Context context){
        super(context, DataBaseName, null, DATABASE_VERSION);
    }

    @Override
    public void onCreate(SQLiteDatabase db) {
        // TODO Auto-generated method stub
        db.execSQL(REGISTER_TABLE_CREATE);
    }
public DbFav open() throws SQLException{
    db = DBHelper.getWritableDatabase();
    return this;
}
public void close(){
    DBHelper.close();
}
public long insert(String  Name,String Address ) {
    ContentValues initialValues = new ContentValues();
    initialValues.put(ColNam,Name); //key , value
    initialValues.put(ColAdd,Address);
    Log.i("Values Inserted","Values are inserted");
    return db.insert(favtable, null,initialValues);
}

Values to be saved to the DB from below coding which gives the exception of Visitors contain no Col named (Name, Address)

                get_place=trname.getText().toString();
                get_add=tradd.getText().toString();
                db.open();
                db.insert(get_place,get_add);
                db.close();
