I have a ChildID table and a ClinicVisits table. I want to ensure that the
user cannot create a ClinicVisits record that does not have matching values
for ClinicID and ChildID in the ChildID table.

When I try to establish a relationship in the relationships table, it will
only allow me to set up a link for one field between the two tables. How do
I establish a two-field relationship between tables?

I've seen posts about foreign keys and junction tables but I don't quite
understand the foreign key posts and the junction table seems to be for
many-to-many relationships and I am setting up a one-to-many relationship.

Thanks for any help you can give me.
