Index Script From BOL Fails

http://msdn2.microsoft.com/en-us/library/ms188917.aspx
This script keeps failing on line 22 on a ) but i do not see where it is erroring.

I put in USE DBNAME
and run it and it fails.

Any suggestions
The script under D:
D. Using sys.dm_db_index_physical_stats in a script to rebuild or reorganize indexes
The following example automatically reorganizes or rebuilds all partitions in a database that have an average fragmentation over 10 percent. Executing this query requires the VIEW DATABASE STATE permission. This example specifies DB_ID as the first parameter without specifying a database name. An error will be generated if the current database has a compatibility level of 80 or lower. To resolve the error, replace DB_ID() with a valid database name. For more information about database compatibility levels, see sp_dbcmptlevel (Transact-SQL).
