I am a Filemaker amateur and this is my first question ever, so pardon me if this is silly.
On a layout for ::Unit, I created a portal to enter photo into a table called ::Image, I used an Ophan table called ::Image_Unit. it worked fine!
On a layout for ::Building I created a similar portal to enter photos on the table ::Images, this time using an orphan table called ::Image_Building
The portal on ::Building, refuses to work, and the portal in ::Unit it now says <Unrelated Table>
