I am attempting to build a simple list, but can't seem to get it to work.
Could someone please help me with this problem?

writeln(S):-
	write(S),
	nl.

query:-
	writeln('Enter the verticies'),
	querytop(L),
	write(L).

querytop(L):-
	read(A),
	query(A,L).

query(end,_):-!.

query(A,L):- 
	L=[A|L],
	writeln('Another one...'),
	querytop(L).



I read the stuff, but it isn't being put in the list, it stops after entering
2 numbers.  Why isn't it working?
