I am stuck on the Process Automation Trailhead - Customize How Records get Approved with Approvals:
"Create an approval process that validates when a Prospect Account becomes a Customer."

I did everything in the notes before trying the challenge.
I started a new Approval Process under Account as I believe the instructions mention. I am not sure what is wanted for the "Specify Criteria" section as I don't see it being asked for in the Challenge, but it seems to be a field that wants to be filled out? Please help!
