I have this relationship: Patient-----<Interaction
Interaction::VisitDate is on a portal row, on a layout based on the Patient table.
A second instance of Interaction::VisitDate is on the same layout outside the portal.
When I click on an Interaction record row in the portal I want the second Interaction::VisitDate instance, the one outside the portal, to update to the the value of Interaction::VisitDate in the row I clicked.
This sounds simple but I can't get it to work. I could put a popover button on each row but I'm trying to avoid using a popover so all of the data is visible at once.
