We are trying to use Approval Routing for our Expense reports but are having no luck in getting it to work.  We have enabled Expense Reports, checked Expense Reports under Approval Routing and notifications have been turned on.  Supervisors set and expense limits and approval limits set.  Yet, when expense report is entered, no notification is sent to supervisor, next approver is not set and when the supervisor goes into employee center does not see option to approve.  What are we missing?  I have looked at documentation and it seems we have everything set and yet nothing.

Any help would be greatly appreciated.
