I'm creating a form in SharePoint using Person Group field with option to add multiple. In the Nintex workflow, for each of the employees defined in the Person Group field, I need to run Query User Profile to look up their manager and store it in a variable. It works when I have one employee defined, but when I have two or more, it only looks up the manager of the first employee. How can I use the "For Each" function in the workflow? I'm very new to Nintex!
