What function has the booking calendar field in "Show instance layout"?
One cannot click anything and and nothing special gets displayed except an empty calendar.

In OS Joomla CCK Every Instance is ready:
- For show
- for buy - You need connect to "show instance layout, "Buy request layout"
- for request - - You need connect to "show instance layout, "request layout"
- for booking, so in "Show Instance Layout" you to instance may add "Rent Request layout", every client may ask for booking this instance, and admin or instance owner - may approve this "booking request". Or admin may move this instance to rent - in admin area->CCK instance Manager.
When instance moved to rent, - it appear at "Booking calendar" so other people may see when Instance is busy and they will send rent request for free times

Now it is more clear. Thank you.

I didn't switch the "Rent from date field" to the field type "Rent from" and the "Rent to date field" to the field type "Rent to" in the main option menu of the "add rent request layout". Both were set to "default". I didn't know that one has to change it for this purposes.

I have set the type fields to Rent to and Rent from in the rent request layout.
Unfortunately I cannot choose anymore any date with the cursor. The calendar doesn't get displayed when i click on the "rent to" or "rent from" field. I have to type the dates with the keyboard into the fields.
Is it normal?
