Google Calendar: Is it possible to check if the block of time is available?

How about having the ability to check if the block of time about to be created is available ?

What is the behaviour of the form, if already accounted for ?

Otherwise, I could see many form submissions overlapping and creating a mess, if used as shown in the screen captures ("booking from" and "booking to").

JotForm is growing in leaps and bounds. Fantastic.

I'm afraid current Google Calendar integration does not have an option to check availability of time slots yet. Every new submission will add an even to your calendar. But, I am submitting a feature request for our developers to consider adding such option.
