Help With Reporting WITH SQL

HERE IS THE CHALLENGE:

In an ecommerce database there's an orders table with the columns id, product_id, user_id, address_id, ordered_on, status and cost.

Count the total number of orders that were ordered yesterday and have the status of 'shipped'. Alias it to ordered_yesterday_and_shipped.

Type in your command below, then press Ctrl-Enter.

HERE IS MY ANSWER:

SELECT COUNT(ordered_on) AS ordered_yesterday_and_shipped FROM orders WHERE status = "shipped" AND DATE("now", "-1 day");

Very close! You computed the correct day, but forgot to do the actual comparison.

... AND  ordered_on =  DATE("now", "-1 day");
