We are looking to set-up the following functionality in Marketo for a Preference Center form. We currently have 4 checkboxes on the form - 3 checkboxes are types of communications to Opt-In to receive, and 1 checkbox is an unsubscribe. If unsubscribe is selected, the other 3 checkboxes should be false. If 1 or more of the 3 opt-in checkboxes is selected, the unsubscribe should be false. Looking for assistance on implementing this functionality. Thank you!
