I have just started on my Erlang journey and am struggling with a compiler
error that I am hoping someone with experience can spent 5 secs and tell me
what i'm doing wrong, as I am not very good at understanding what the
compiler is telling me.  Thanks!

I am passing in a string such as "morning, 1, 2, 3" as the UserEntry and
simply want to create a variable which holds a list of the tokens.  I am
getting a message from the compiler saying "syntax error before: 'case'.

-module(practicum).

-export([placeorder/1]).

placeorder(UserEntry) ->
  AllTokens = string:tokens(UserEntry, ",").

  case hd(AllTokens) of
      "morning" ->
      processMorning(lists:nthtail(AllTokens,2));
      "night" ->
      processEvening(lists:nthtail(AllTokens,2));
      _ -> io:fwrite("error\n")
end.

processMorning(Dishes) ->
     Dishes.

processEvening(Dishes) ->
     Dishes.
