Hi Tong, I don't have an immediate solution to your problem, BUT, I saw a thread from a month ago that may help... https://teamtreehouse.com/forum/error-3 Also, try copy/pasting your error message into Google (or the search engine of your choice). There may be some helpful info there as well. Good luck!
