AndroidのSQLiteの接続の際にこんなエラーが出ます。

２つのクラスがえらーメッセージに書いてあったので、コードをのせました。
"tableusers": syntax error (code 1): , while compiling: create tableusers(_idinteger primary key autoincrement,nametext,scoreinteger)
このように書いてあったので、tableをcreateするときの、文法や、名前を何度も確認したのですが、ミスは見当たりませんでした。
どこが間違えているのでしょうか?

アドバイスの方をどうかよろしくお願い致します。

            Log.v("DB_TEST","id"+id+"name:"+name+"score:"+score);
        }

        c.close();
        //close db
        db.close();
