Modifying Data with SQL Challenge question

Please can someone assist.

I am stuck on task 1 of 3: https://teamtreehouse.com/library/modifying-data-with-sql/adding-data-to-a-database/adding-data-with-sql

I have written the following code.

INSERT INTO products (id, name, description, price) 
VALUES 
(1, "Sarah", "Red", 10.99), 
(2, "Niamh", "Blue", 22.99), 
(3, "Elle", "green", 22.22), 
(4, "Brad", "purple", 10.22);

And it's giving the following error:

Bummer: Was expecting 4 entries in the products table. There's only 3.

Here's a few hints:

  • the instructions only ask you to add one new product
  • they warn you that the ID column is auto-incrementing
  • an auto-increment column should be given a NULL value (or just not be included at all)

Thank you for your reply!

I have tried entering one product: 

INSERT INTO products (id, name, description, price) 
VALUES 
("Sarah", "Red", 10.99);

It's still giving me the same error as above.

I've just realised I was including ID in both, when I didn't need it in either! Have fixed it, thank you!
