Expense Management approvals

Am using expense management approvals and am trying to setup up the workflow so that a report where TOTEXP is less than 500.00 is automatically approved. I am using an EA structure with TOTEXP as the associated data item. I have several level 1.00 records and 1 level 2.00 record with a 500.00 threshold in the structure. Right now, all of the approvals are stopping at the level 2 and sending approval required e-mails regardless of the expense report amount. Any ideas?
