Hello. Usually when creating and working with subordinate forms there are no problems. But in this case, something does not come out. You need to create a form for the report of the work of the employee for the day, which will look like this: 
Initially, the problem was to create a form in which time would be entered (on the left side of the table). I solved it by creating a time table with attributes (8:30, 9:00, etc.). Created tables, linked, but the subordinate table is populated separately.
and, although there is a link in the subform, the key_time attribute in the manager_report table is not populated 
An error pops up
