You are very close! Two errors to fix:

  • there is an extra colon (:) on the route line
  • the argument to url_for should be the name of the endpoint function and not the equivalent URL path to the function. Otherwise, if you already know the URL path to that function, you could redirect directly there and not need to use url_for.

Post back if you have more questions. Good luck!!
