Well you've deleted the portion of the code referring to x and y.
listPairs = [(a*b, y) | y <- [0..], a <- [0..], b <- [0..], (a*b) > 5,
(a*b) < 500, (y*y) < 1001, mod y (a*b) == 0]
This will still never terminate however.

thanks to both!
listPairs = [(a*b, y) | a <- [0..], b <- [0..], (a*b) > 5, (a*b) < 500, (y*y) < 1001, mod y x == 0]
Now I have it as you said, however the compiler complains about all y and x and says they are NOT in scope.
Why is it so? I can't see any problem with that...
