Leave Approval / Reject Rules

Leave Approval / Reject Rules

I'm trying to set multiple approvals for rejection/approval PTO requests base on date requested. I have tried multiple ways and can't seem to make it work. Maybe someone can tell me how they would set it up?

Here is what I need,

-------------------

If PTO falls in this date ranges 05/01/2018-05/31/2018 
      Auto Deny
      End
If PTO falls in this date ranges 11/01/2018-11/30/2018
      Auto Deny it
      End
Else
      Send to Role-based approver.
      End

-----------------------------

Any suggestions?
