cannot create any player

[blacksystem]

I tried out a register script, but no work

So i tried to insert a new user by odbc management on query, and isn't working

INSERT INTO dbo.tUser
    (sUserID, sUserPW, sUserName)
VALUES
    (username, password, username)
GO

then it shows

The column name 'username' isn't valid

i'm being crazy trying to figure out how fix x.x
