I created a form with a radio group field and a checkbox field. And I have a date intervall field.
The radio group has this options:
1=desk1
2=desk2
3=desk3
4=desk4
5=desk5
I want tot do as follows: No double booking for the options desk1-desk5. If the checkbox is checked the booking for the options 1-5 is no longer possible. If there a desks already booked you cannot check the checkbox. Checking the Checkbox= all desks are booked.
I can`t figure out the rule that would makes this work properly :-(
