How do I "turn on" approval levels for workflow based on Refinement Templates and Exp Location Amoun

The way we have our system set up expense reports will either route only to the HR Supervisor or to both the HR Supervisor and the Prepay Auditor based on the expense location amount and the prepay auditor refinements that are setup.

For example in Image 28, the expense location of expense type is breakfast DALL and the location amount for breakfast has an active average amount of $13.10.  The prepay auditor refinement is setup to send expense reports for audit review when the location amount has been exceeded (Amount Exceeded box is checked).  The Expense Manager has nothing selected on the refinement template.
