Working on TrailHead Challenge... (https://developer.salesforce.com/trailhead/force_com_introduction/data_security/data_security_sharing_rules)

Tasks completed:
The custom object must be named 'Project' with a resulting API name of 'Project__c'.   Done
The Name field for 'Project' must be of type Text (not Auto-Number).  Done
The custom object 'Project' must have a custom field of type picklist named 'Priority' with a resulting API name of 'Priority__c'. Done
The role label should be 'Training Coordinator' with the resulting 'Role Name' of 'Training_Coordinator'. Note that you may already have this role in your role hierarchy from a previously attempted challenge.   Done
Set the organization wide settings to public read only.    Done

Here is where I think is the problem:
The sharing rule can be named anything.  
 Create sharing rule under "Sharing Settings" under Project Sharing Rules..  Create a criteria based project sharing rule with Priority custom field equal to High.  Shared with role "Training Coordinator" as read-only access.


What am I missing?
