I am working on the Salesforce1 Mobile Customization Badge and am in the module for the object specific quick actions. I have followed these steps:

Create a quick action on the event object for entering a prospective buyer's feedback
Your brokers want to capture the feedback of their potential buyers after they look at a property. Create a quick action on the event object so brokers can update an event with their notes immediately after a showing. Add the action to the publisher for the Showing layout.
Create a quick action for the event object
Action type: Update a Record
Label: Enter Feedback
Remove all the fields on the page layout except for Name
Put the Feedback field on the page layout
Add the Enter Feedback quick action to the publisher for the Showing Layout. You might have to override the predefined actions in the Salesforce1 section of the publisher.

And have this action done with layout streamlined:


And the placement of the action:



But I still get this error for Name and Feedback missing? 



If anyone can help, that would be greatly appreciated. I am not sure what I am missing. 

The challenge as follows:

For purposes of local regulation new customers must be approved by the legal team.

When an Account has the value of 'Prospect' in the Type field, a user will click the 'Submit for Approval' button to launch an approval process. The process will only happen if Type is 'Prospect' and there are more than 500 employees. Upon entry of the process, Type will become 'Pending' and be locked. If approved, Type will be set to 'Customer' and be unlocked. If not approved, Type will be set back to 'Prospect' and will be unlocked.

The Account object's Type field must have the following picklist values: Prospect, Customer, Pending. Before creating the approval process, verify the values in your Account object setup
The approval process name must be 'Approve New Account'.
When user click 'Submit for Approval', the approval must be processed if the Type field is set to 'Prospect' and the value of Employees is greater than 500.
Upon entering the approval process, set the Type field to 'Pending' and lock the record.
Normally the approver would be someone else. In this instance, assign yourself to be the approver.
If approved, set the Type field to 'Customer' and unlock the record.
If not approved, set the Type field back to 'Prospect', and unlock the record.

I am getting error message: Challenge not yet complete... here's what's wrong: 
There was an unexpected error in your org which is preventing this assessment check from completing: System.DmlException: Process failed. First exception on row 0; first error: REQUIRED_FIELD_MISSING, missing required field: [nextApproverIds]: [nextApproverIds]

This are the steps I did:

Created approval process called Approve New Account
Criteria Account Type field equals Prospect and Account Employees field greater than 500
Final Approval Actions - Update Type field to Customer
Final Rejection Actions - Update Type field to Prospect

What am I missing that I received the error message?  Please help.

Thanks.
