  1. “done compiling” is not the same as “done uploading”
  • Make sure that you are clicking on the “upload” button and not the “compile” button.
  1. “expected declaration before '}' token
  • You have too many brackets in the code. Make sure every closed bracket corresponds to an open bracket.
  1. “expected '}' at end of input”
  • You are missing a bracket in the code. Make sure every open bracket corresponds to a closed bracket.
