I need to know how to get a field in a query to indicate by "yes" or "No" whether records exist in a child table of one of the tables in the Query. As yet the child table is not represented in the query.
I have tried wrapping dCount() in IIf() but no luck:
iif(dCount("ChildTable.Key","ChildTable","ChildTableKey = ParentTable.key") > 0,"Yes","No")
The query populates a listbox
