Hello!

```
In the lesson 'Inserting Hierarchical Rows' I am having trouble following along with this exercise. I have entered the code the same way as on the screen but when I go to execute it gives me the Error Code 1452 cannot add or update a child row. I'm not sure what I am doing wrong in this instance. This is the code that I have entered:

```

INSERT INTO orders(  
customer\_id,  
order\_date,  
status)  
VALUES (  
1,  
‘2019-01-02’,  
1);

INSERT INTO order\_items  
VALUES  
(LAST\_INSERT\_ID(), 1, 1, 2.95),  
(LAST\_INSERT\_ID(), 2, 1, 3.95)

Any assistance in this would be greatly appreciated!
