Hi Shadow...
Yup, I see what you mean. I have since posting found this but am still having problems.
I have it so that the student_id is now copied, which is great. FM doesn't seem to want me to add data in any fields from these other tables for some reason. It insists that the relationships are invalid or, if I can get one field to accept input, it won't allow entry in any other. I've tried doing this with either just regular fields or using a portal with no luck.
I just hope The Shadow knows...
Cheers
