When trying to import the file for this activity I watched the recorded session and did exactly what was said, I also followed the steps from lesson 4 but for some reason it keeps saying the file isn't successful because of invalid names. It says 1 updated and 12 failed. I'm not sure where I went wrong!
I saved the document provided by lesson 4 and just tried to upload it again but I am still having troubles. I dont want to move forward without a successful import.
