Your code looks good except that where I would expect to see the list field "_numbers
", you have "number
" (and thus the error). And in the places (3 of them) where I would expect to see the name of a temporary variable (such as "number"), you have the name of the list field.

you're selecting the IEnumerable
. Do select number
instead.

You got the other 2, but you forgot to change that last "_numbers
" to "number
".
