SQL Update Error in Microsoft Access

Hi,
 
I'm creating a Raffle Program using VB6.
I'm having trouble updating the data in MDB. This is the error when executing the SQL
Data type mismatch in criteria expression.

UPDATE WINNERS SET PrizeClaimed='1' WHERE RaffleNumber=461 AND [Date]='11/21/2012 11:12:52 PM'; 

 
This is the query I use in adding the record. Don't know why the above SQL won't run. I just add record using the same dates '11/21/2012 11:12:52 PM'

INSERT INTO WINNERS([RaffleNumber], [PrizeClaimed], [Date]) VALUES('461', '0', '11/21/2012 11:12:52 PM');

 
Can anyone post why this happens...
 
Thanks
