In this edit I merely swapped the code that the answerer intended, as he copied the wrong portion from the page he linked. The edit got rejected, and I'm not sure that was beneficial to the community. The answer currently offers the opposite of what the question asked for, and only because of a mistake copying the code. I don't understand... who benefits from this? Or who would be harmed if the edit was approved? Shouldn't the main goal of any Q&A site be having useful and correct answers for the OP and other visitors who have the same question?
