Can I insert into the same table a new row with the "old" row field value?

I'm trying to insert values into the same database from itself.
Essentially, I want to add another row to the table for each row with
reg_cat_id = 3. But in this row, I want the original registration_id
to show up in the new row.
Here is my syntax below - this generates an error:
INSERT INTO Registration_Category
(REG_CAT_ID, REGISTRATION_ID, STAFF_ID,
REGISTRATION_DATE, APPROVAL_STATUS, APPROVEDDATE)
VALUES (90, t1.REGISTRATION_ID, 'test', '05/05/2007', 'Y',
'05/05/2007')
SELECT REGISTRATION_ID, STAFF_ID,
REGISTRATION_DATE, APPROVAL_STATUS, APPROVEDDATE
FROM Registration_Category t1
WHERE (REG_CAT_ID = 3)
ORDER BY REGISTRATION_ID
Any suggestions?On 30 Mar 2006 14:40:12 -0800, Dee wrote:

INSERT INTO Registration_Category
(REG_CAT_ID, REGISTRATION_ID, STAFF_ID,
REGISTRATION_DATE, APPROVAL_STATUS, APPROVEDDATE)
SELECT 90, t1.REGISTRATION_ID, 'test',
'20070505', 'Y', '20070505')
FROM Registration_Category AS t1
WHERE REG_CAT_ID = 3
