I've added all these line of code in the Save() method to try to satisfy the "Modify the save() function to implement CRUD/FLS check on the Name field of the Encrypt_Decrypt__c object." requirement but nothing seems to pass it's check.  Anyone else run into this or have any ideas?

        if (!Schema.sObjectType.EnCrypt_Decrypt__c.fields.Name.isCreateable()) { 
            return NULL; 
        }
        if (!Schema.sObjectType.EnCrypt_Decrypt__c.fields.Name.isUpdateable()) { 
            return NULL; 
        }        
        if (!Schema.sObjectType.EnCrypt_Decrypt__c.fields.Name.isAccessible()) { 
            return NULL; 
        }        

Thanks,
Deb
