Try deleting the relevant lines of code and then write them again, actually type them again, without referring to and especially not copy'n'pasting code from somewhere else. Sounds stupid I know, but I've given this advice many times over the years and it has an extremely high success rate in the situation you're describing. MSB -- Light travels faster than sound.
