I believe the problem was caused by putting an action in the wrong section. I deleted it, and added it correctly, or at least I think it's correct. But the challenge doesn't seem to think so.
I'm getting the following message.
The final approval is not configured correctly for 'Discount Approval Process'. Approving the opportunity did set the opportunity's Approval_Status__c field value to 'Approved'.
The problem was that I deleted the action and created a new one. I should have just added an existing action to move it to the correct section. By creating a new action, the verify logic did not see the correct code.
I started over in a new org, and did the steps correctly and got the badge. All the steps look the same, except I carefully put them in the right spot from the beginning, and didn't attempt to create a second action that does the same thing.
