231,248 PointsIt's probably the columns, not the data.
You forgot to include a link to the challenge page, but based on the results including the last name, I'd bet the entire thing was not supposed to be concatenated together and given the alias "initial".
Read the instructions again carefully, and I expect you will find that the alias "initial" was supposed to be only for the result of the SUBSTR. And the last_name was probably intended to be a column on it's own.

231,248 PointsSo I guessed correctly! 
As I suggested before, the alias should apply only to the first letter you extract from first_name, and last_name is just a normal second column. This challenge does not use any concatenation.
