Hi, I am trying to create an event and select a few contacts from the contact list. How do I achieve this?
I’m going to need some more info than this to work from to help 
I am building a gift planning app where a user can create a gifting event (ex: Christmas) and assign selected contacts to the event to receive a gift from him.
I was able to achieve the first part when I can select contact one at a time and create a new collection “Event Recipients”, but if I select the same contact twice, there are duplicate entries in the collection. (screenshot attached below)
How can I ensure that no duplicate contacts are assigned for the same event? Thanks in advance.
You could use Conditional Actions to achieve this.
