I did spot a few errors here and there, first write out numbers, it adds a level of professionalism, at the start it was a little rough but as it progressed it smoothed out a bit. over all its very detailed and a way to take care of the question mark symbols is to paste the work to note pad and use the replace feature to change them over to a compatible symbol. I know that certain web pages don't like fancy fonts and symbols like opening and closing quotes or "..." I know that microsoft word likes to turn that into its own symbol
