Erlang syntax error before: 'end' in line 55 - erlang

Question

Cant find the syntax error, i searched for misplaced/missing ";" , "," , "end" and also searched for missing parentheses but no luck.
Any ideas?
PD: Sorry for bad English and Spanglish code
partida(ID,Tablero,Turno,Name1,Psocket1,Name2,Psocket2,SpectList) ->
case (Psocket1 == " ") of
true -> F = fun() -> case mnesia:read(juegos,ID) of
[P1] ->
case mnesia:read(nombre,P1#juegos.jg1) of
[] -> exit(normal);
[A] -> P2 = A#nombre.psocket
end,
case mnesia:read(nombre,P1#juegos.jg2) of
[] -> exit(normal);
[B] -> P3 = B#nombre.psocket
end,
Res = {P1#juegos.jg1,P2,P1#juegos.jg2,P3,P1#juegos.spect};
_ -> Res = ok,exit(normal)
end,
Res end,
{atomic,Arg} = mnesia:transaction(F),
partida(ID,Tablero,Turno,element(1,Arg),element(2,Arg),element(3,Arg),element(4,Arg),element(5,Arg))
end,
receive
case Jugada of
[Pj,"bye"] -> ok;
[Pj,F] -> Posicion = element(1,string:to_integer(F)),
case (Name1 == Pj) and ((Turno rem 2) == 1) of
true -> case not(Posicion == error) and (Posicion < 10) of
true -> ok;%%jugada valida
_ -> ok %%Jugada ilegal
end;
false ->ok %%No es tu turno
end,
case (Name2 == Pj) and ((Turno rem 2) == 0) of
true -> case (not(Posicion == error) and (Posicion < 10)) of
true ->ok; %%jugada valida
_ -> ok %%Jugada ilegal
end;
false -> ok %%No es tu turno
end
end
end, %% Line 55
ASD = get_spects(ID),partida(ID,Tablero,Turno,Name1,Psocket1,Name2,Psocket2,ASD).

Answer 1

You have a syntax error in receive clause.
1> case oops of _ -> ok end. % correct
ok
2> receive (case oops of _ -> ok end) end.
* 1: syntax error before: 'end'
receive statement is used for reading Erlang messages of the process. Here you are not waiting for any message and you are doing something in body of receive clause! If you don't want to check the message but you want to do something after receiving first message, I recommend to use _ for pattern matching:
3> receive _ -> (case oops of _ -> ok end) end.
%% Waits for a message
Actually you can have no receive clause, but like this:
4> receive after 1000 -> done end. %% Sleeps 1000 ms and does not care about any incoming message
done
But you can't write code in receive clause without any pattern matching.
