When reading through the comments of this question, I found out that the problem had already been resolved, though no answer was given. Apparently the cause of the problem was the OP's oversight only.
Should a question like this be flagged? If so, with what type of flag? Not a real question or not constructive? Why?
Or should one add an answer of the form "There was no problem in the question, OP was making some mistake elsewhere" or something else?
