I am inferring this relationship:
Speeches----<Events (One speech record can be linked to many events.)
Define a field of type calculation in your Speeches table. Do not use a number field with an auto-entered calculation as it will not update automatically when you add/remove related records.
Use the count() aggregate function to count the number of related records:
Count ( Events::AnyFieldthatIsneverBlankcanbeusedhere )
Perfect! Thank you so much. You've always come through :)
