Hello @Ed80,
On your calendar the 6th of January is available and all dates from the 4th of February onwards are shown as available.
To set all dates except a certain week as unavailable you can set all dates as unavailable by default and then manually set that week as available.
To do this you can
go to your calendar and click on "Availability" at the top
click on the "Edit" button for the "Reservation preferences" section
scroll down to see the "Booking window" box
click in that box and select "Dates unavailable by default"
now click on "Save".
Now go to your calendar again and click on the first date you want to set as available.
A window will appear on the right. Click on the date to the right of the arrow and select the last date that you want as available. Then click on "Save".
Remember that if you select, say, the end date as the 10th then guests can check in on that date and check out on the 11th.
Regarding the problem with responding I'm not sure what could be happening there. If you're trying on a on the web page on a laptop or in the phone app perhaps you could try by using the button in the email instead.
Steve.
