A prolog question

I'm trying to implement a nice piece of prolog code using SWI-Prolog which should work, however I'm obviously missing something because all I get is the error message "Syntax error : Operator Expected."

The code is :

request :- ( , X, Y, Z), person :- X, iceCreamType :- Y, topping :- Z, !.

it goes on to fill out the details like :

request :- (1, jimmy, vanilla, hund_thou).
request :- (2, alice, vanilla, hund_thou).
.
.
.
and so on going through the possibilities. If anyone could shed some light on this problem I would appreciate it smiley - ok
