My solution to the question is exactly what has been provided, but whenever I input the first and last name values, It always returns a null value. Why is that?

Hi Edward! Thanks for reaching out. Please, check if your tables are empty. You can use the SELECT statement for the employees table. Hope this helps. Best, Tsvetelin

The tables are not empty, but I also realized that whenever I copy and paste the solution provided, it works just fine and its the same as what I have.
