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。

Caused by: android.database.sqlite.SQLiteException: near "tableusers": syntax error (code 1): , while compiling: create tableusers(_idinteger primary key autoincrement,nametext,scoreinteger)

SQL文の"tableusers"という単語の近くにエラーがあるといわれています。
while compiling～を見ると「create tableusers(_idinteger primary key autoincrement,nametext,scoreinteger)」というSQL文でエラーになっていることがわかります。

Java
1public static final String CREATE_TABLE=
2            "create table"+UserContract.Users.TABLE_NAME+"("+
3                    UserContract.Users._ID+"integer primary key autoincrement,"+
4                    UserContract.Users.COL_NAME+"text,"+
5                    UserContract.Users.COL_SCORE+"integer)";
