I am at the "Add the Reusable Interface" step on page 4 of exercise 10. I am running into an "Invalid index" issue when trying to update the expression after dropping in the W1570SA_VehicleDetailsView into the Vehicle Details section. This is what I type into the expression box "r!maintenance[recordType!W1570SA Maintenance.relationships.vehicle]" - the error that pops up is "Invalid index: Cannot index property 'relationships' of type Text into type RecordType"
When I try to click the suggested items that pop up, vehicle isn't even listed under the relationships (second screen shot)
