I cannot see what is wrong with my code

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.

The -1 in the DATE function has to be in quotes and according to the video I add the string days to it so it looks like

DATE('now', '-1 days')

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