Hello Miroslav! Please post your code so that we can see whatโ€™s happening and then help to troubleshoot. In the future, when posting via the "get help" button from a challenge, please make sure "Attach my code with this post" is checked.

I've seen where folks get this message and the problem is either the wrong number of columns are being returned, or the column alias is missing or incorrect.

Show your actual code line if you need a more precise answer.

Yes, this is also from the number of columns. The alias should be applied only to the "first initial of their first name" column, and when they said "Select their last name too", they meant as a second column. You won't need to do any concatenation for this challenge.

select substr(first_name, 1, 1) || " " || last_name as initial from customers

In an ecommerce database there's a customers table with id, username, first_name, last_name, password, email and phone columns. Create a report from the customers table that shows their first initial of their first name and alias it as initial. Select their last name too.

Bummer: Expecting results like 'L Chalkley' not 'L Chalkley'.
