problem with lists?

[pnwamk]

This could be a silly mistake on my part, but I seem to be unable to operate on lists via the REPL on http://try.racket-lang.org/.

For instance, entering (list 1 2 3) or '(1 2 3) in the REPL gives the following error (printed twice):

application: not a procedure;
expected a procedure that can be applied to arguments
given: 1
arguments...:

3
