How to set up a minimum number of nights

[cathc]

I can’t seem to access a way to set a one-week stay as a minimum. These directions don’t work:
“Go to Your Listings > Manage Listing and Calendar > Calendar and click Settings .
You’ll be able to set the minimum number of nights a guest’s reservation can include, and the maximum number of nights it can include. When you set either term, it will automatically save. You can also add requirements for seasons or weekends.
If a guest tries to request a reservation that isn’t within this range, we’ll let them know what your terms are and encourage them to adjust the dates of their request, or look for a different place to stay.”
