Periodic Table Project (DB) - delete the non existent element,

Hi.

For some reason I cant pass the: " You should delete the non existent element, whose atomic_number is 1000 , from the two tables" task. Although I did delete it from elements and properties tables.

When I run the test it says in the error message: “SUBTASKS 1.1 :28 You should delete the rows of the non-existent element from your tables”

It is the last task missing to complete,
What am I missing?

It’s cause you have the atomic_number set as a VARCHAR type @bart, I changed them to integers and it passed.
