Your answer wasn't incorrect, because it didn't give any false
information. Bob and I saw the problem itself and gave advice, but you
gave useful general advice on how to find the problem, which is worth
bearing in mind. Matt, read Joel's response for useful tips on how to
figure out what might have gone wrong. :)
