You ORDER BY mem.firstname, while the solution uses member. What is important here is that, member not only contains that firstname, but actually that exact thing the error message hints at:

ERROR: for SELECT DISTINCT, ORDER BY expressions must appear in select list

Interpretation: When selecting a distinct value, all expressions in your GROUP BY must be distinct.

So, the reason for the error, is because you tell it to order by only the first name, and that attribute must be what you said to be DISTINCT in the SELECT clause. But it isn't, it is partially there, but there's also: ' ' || mems.surname
