How to transfer data from one table to another?

I have a temporary shoppingcart-table that I want to transfer to an OrderDetail-table. See following code:

CREATE PROCEDURE add_orderdetails
@.CartID int,
@.OrderID int

AS
BEGIN TRAN AddOrderDetail
INSERT INTO OrderDetails
(OrderID, ProductID, Quantity, Price)
VALUES
(@.OrderID, SELECT ProductID, Quantity, Price FROM Cart WHERE CartID=@.CartID)
COMMIT TRAN AddOrderDetail
GO

The OrderID and CartID are inputs from an asp-page.

I got an syntax-error near SELECT and ')'.

I hope someone is able to help me with this. I will be very grateful!I helped myself. If I remove the VALUES, and put the SELECT-sentence like this:
SELECT @.OrderID AS OrderID, ProductID, ....

Jippi :o)
