On page 103 it asks you to look inside MatchingGameObject7.fla. There is no such animal. There is only a MatchingGame7.fla and a MatchingGameObject7.as. As you read on after that down the page and through to 105 it becomes obvious why, and that the 'MatchingGameObject7.fla' is a typo. Just go ahead and open 'MatchingGame7.fla' at the top of page 103 and follow along. Hopefully this is will save someone the searching I just went through.
