Workflow notifying a manager their employee was added to a group.

I have a workflow in activeroles 7.4, notifying a manager their employee was added to a group. Can someone please help me with the correct code in the email notification so it can not target the group but instead the user being added to the target group? 

I was using

<% =Operation.Target["samAccountName"] %> 

But this just says the group name and doesnt show the employee name.  I just need the manager to know the employee name in the notification email that was added to the target group.  thanks.
