I have a custom object called Engagement__c that has Account__c. Account__c has a field called Name. The relationship between them is that Account__c is a lookup field in Engagement__c. I want to create a simple formula field in Engagement__c that gets the Name of Account__c.
Account Name (text):
Account__c //Works - no syntax error Account__c.Name //ERROR - Field Account__c does not exist. Please check spelling
