Can't insert integer type to DB

I'm having trouble using integers in DB. I have a SQLiteOpenHelper here I create

DBAdapter:

public static final String KEY_ROWID="id";
public static final String KEY_EXR="name";
public static final String KEY_WGHT="weight";
public static final String KEY_REP="repetition";
public static final String KEY_DATE="duedate";
final static String[] columns = {KEY_ROWID, KEY_EXR, KEY_WGHT, KEY_REP};



   final static String DATABASE_NAME = "ExerciseDB";
final static String DATABASE_TABLE = "exercisetb";
final static int DATABASE_VERSION = 2;


//DBAdapter için Loglar

private static final String TAG = "DBAdapter";



private static final String DATABASE_CREATE =
        "create table if not exists exercisetb (id integer primary key autoincrement, "
                + "name VARCHAR not null, weight VARCHAR not null, repetition integer not null);";

Inserting:

  public long insertRecord() {


            ContentValues values = new ContentValues();

            values.put(DBAdapter.KEY_EXR, name.toString());

            values.put(DBAdapter.KEY_WGHT, weight.toString();

            values.put(DBAdapter.KEY_REP, Integer.parseInt(repetition.toString()));
            values.clear();

            return mDbHelper.getWritableDatabase().insert(DBAdapter.DATABASE_NAME, null, values);

        }

The problem occurs on last variable. We can put KEY_EXR; KEY_WGHT but not KEY_REP. If I change KEY_REP column to VARCHAR only then I can add data to that line. I 'm probably making mistake during table create.

Thanks.
