I'm using Nintex 2010 and SharePoint 2010 and trying to redirect the user back to the list after approval. I find this answer on here but I can't find the Approval URL when I go to Insert Reference with the task, do I need a different approach or am I doing it wrong? 
Redirecting the user back to the list after a task has been approved
+10
+9In 'Assign Flexi Task' action go to 'Task Notification' action and place your mouse in email body and click on 'Link' from 'INSERT' at the top of ribbon, you will find it.
If you not find, Use 'Redirect Url' option on 'Ok' button from 'Task Form' to go back your list instead task list.
After adding ApprovalURL type "&source={Common:WebUrl}"
that will direct user to site home page after completing the task
+10I can't see the ApprovaURL reference, see the screen grab in the original post, it doesn't appear. Any other reference I could use?
so you are inside the flexi task action configuration on the "Task Notification" tab in the ribbon?
