I'm looking to create some form logic that hides a control based on which SharePoint user group the user belongs to. i.e. if userx belongs to the booking group then the form variable is set to "Booker" or if the user belongs to the approver group the form variable is set to "Approver".
I'm fine with setting the hide control operation but I'm not sure as to how to retrieve the users permissions/groups from the SharePoint site.
P.S. I've been looking at Nintex forms for a total of 2 days so any pointers to resources would be much appreciated.
