I followed exactly the 3 steps in this Lab:
1 - Creating a Spreadsheet (although the link in the lab was broken, too, I was able to generate the spreadsheet).
2 - Create the App with the correct name.
3 - Using the App's interface, add a new contact.
Steps 1 and 2 were completed easily, step 3 doesn't check even when I restarted the lab and tried different approaches.
