You now have a mixed queue of access and configuration data work. Each request gives the result the next person needs, without naming every control. Read the table and field names before you make changes. A saved definition and the records it returns both matter.
Work through each task independently. Earlier filters and records reset between tasks, so a prior answer can't supply a later result. Check blank references, closed records, duplicate relationships, and conditions that return no rows. When a result is empty, inspect the definition rather than adding a record to make the screen look busy. Use the hints only after you have compared the requested outcome with the current state.
