I'm trying to complete the challenge in the admin trail about the report builder but I'm stuck. No matter what I try I keep getting the same error: "Challenge not yet complete... here's what's wrong: Please check that you have a filter for Stages that are not equal to Closed Won or Closed Lost."

I tried applying these filters:

Filtered By:1 AND NOT(2 OR 3)
    1. Amount greater than "25,000" 
    2. Stage equals Closed Won 
    3. Stage equals Closed Lost

Filtered By:
    Amount greater than "25,000"
    AND Stage not equal to Closed Won
    AND Stage not equal to Closed Lost

Any help is much appreciated
