Lab 2b

I am under Platform Tools, User Interface, Tabs. I see the Custom Object Tabs section, and I clicked New Object. It throws me an error message on the page stating "Page not found. The page you requested was not found, or you do not have permission to view this page."This is the same account I have been using throughout the course. When I click the Object Manager drop-down menu, "Meetings" shows up, but it still throws the error page when I click New Custom Object. Please let me know how to fix this.
