I am baffled why my code is not working. Count and date problem

https://teamtreehouse.com/library/reporting-with-sql/date-and-time-functions/calculating-dates-2 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.

MY code: SELECT COUNT(status) AS ordered_yesterday_and_shipped FROM orders WHERE status = "shipped" AND ordered_on = DATE("now",-1); debugger is saying "count calculation is wrong. was expecting a count of 14"

it wanted ("now", "-1 days") which is different from the video example. Now I see why so many people had problems on this one.

You're very close, Brett! SELECT count(*) as ordered_yesterday_and_shipped FROM orders WHERE status = "shipped" and ordered_on = DATE("now", "-1 day")
