Multiple problems with the condition rules

I would like to make 2 blocks of choices for the reservation of accommodations whose prices change according to the 2 choices. So I created a first “Accommodation” block for the client to choose the type of accommodation. And I created several “Week” blocks corresponding to the “Accommodation” choices.

But, when I set the display conditions (if “Accommodation” = “Homestay” then display “Week – homestay”) it doesn’t work.

Do you have any idea?
