                    }
            }
        }
  
And I am getting the following error.


1.Variable does not exist: NT_Login_Name__c
2.Variable does not exist: Id
3.Variable does not exist: Survey_Taken_Date__c
4.Variable does not exist: Id
5.Variable does not exist: Survey_Taken_Date__c

Will appreciate your help.

Thanks,
