I was involved in some comments on this question and in the process, I noticed that the poster's problem was trivial. They had a single
# where one doesn't belong. They even admitted later in an edit that they merely overlooked the problem because they were tired. Why doesn't this qualify as a "problem caused by a simple typographical error"? My flag for that got declined. The problem most likely happened because of not paying attention while doing copy-paste; that is typographical.
How can I avoid this in the future? This seemed so clear cut to me.
