I'm creating an event request using nintex form and I would like to validate the availability date based on the current events. I don't find the way to do this, any idea?
Thanks in advance
Not sure I understand what you want to develop but can you not use a lookup control displaying the available event dates?
Maybe good to explain a little bit more.
Thanks Christophe, I'll try to explain.
I just want to show a message that says "The chosen date is already reserved".
For instance: John doe comes and fill the form with an event on date 26th from 10AM till 12PM and after that Bob comes and try to fill the form with another event on the same date and the same hour, I want to show a message to Bob that says that John Doe already reserved that date for an event.
