I'm using a Trigger to update the Products table to the current date if the value for that column is null. I have everything yet, when I insert the new values into the table the DateAdded column for it says NULL instead of today's current date. I'm not exactly sure what's wrong and why it isn't working. Any help would be appreciated, Thanks!

```
IF OBJECT_ID('Products_INSERT') IS NOT NULL
DROP TRIGGER Products_INSERT

CREATE TRIGGER Products_INSERT
ON Products 
AFTER INSERT
AS
UPDATE Products
SET DateAdded = GETDATE()
WHERE DateAdded = NULL;

```
