We have a simple custom object related to the "Contact" standard object that records Webinar information. The object name is "Webinars." On that object there is a text field "Name." I need to create a cehckbox on the Contact object that indicates if the contact attended a specific webinar, let's call it "Webinar A." I was thinking a formula here but nothing I try seems to work. Any advice on how to complete this?
