I am building an event system. A user books events. These events will be listed in the database to users list of events. When a user books an event, Bubble should check if this event’ date range does not overlap a date range of one of the user list events.
How can i realize that? If you have a screenshot of an example that would be great.
It would be something like: selected event date range does not overlap users list of events date range. Sounds easy 
But I have no idea how to setup a date range in workflow language.
