Box 1: No. Error message is displayed in line 05. Cannot read properties of null (reading '0') Box 2: No. Error message is displayed. The entity "Trey Research" cannot be found. Specify a valid query, and try again. Code should be parent[0].entityType Box 3: No. Because the parent record can not be retrieved because of parent[0].name.

Parent record and its value will never be retrieved because of the code"parent[0].name". It should be parent[0].entityType. When the code goes in line 06 the Error Message is dislayed "The entity "Trey Research" cannot be found. Specify a valid query, and try again."

True. Didn't catch that initially. Syntax is Xrm.WebApi.retrieveRecord("account", "a8a19cdd-88df-e311-b8e5-6c3be5a8b200", "?$select=name,revenue")
