Tell us what’s happening:

Hello!

So, I made the salon.sh script and all tasks passes but the following two:

  • You can create a row in the appointments table by running your script and entering 1, 555-555-5555, Fabio, 10:30 at each request for input if that phone number isn’t in the customers table. The row should have the customer_id for that customer, and the service_id for the service entered
  • You can create another row in the appointments table by running your script and entering 2, 555-555-5555, 11am at each request for input if that phone number is already in the customers table. The row should have the customer_id for that customer, and the service_id for the service entered

Running these steps manually works just fine.

If anyone could give some help.

I just found out that the time column in the appointments table was somehow too short for the values used in those cases.

Increasing the column size fixed the problem.
