Review your procedures relationship to patient 2. Have you checked the box "Allow creation of records via this relationship" under your procedures side of the relationship?
I got it to work! The problem was that I needed to establish a relationship from Procedures::PatientID.fk into Patient::PatientID.pk. THEN, when I try and establish Procedures::DoctorID.fk into Doctors::DoctorID.pk FM makes me make a 3rd TOC for Doctors.
I was NOT doing this before and it makes sense to keep a relationship into Patients (not Patients2) because the layout is based on Patients (not Patients2).
What I think could be better is the rather useless, nonsensical 'error' message FM provides when the relationships prevent the portal from working as expected.
Onward through the fog.
Thanks for your thoughts.
