Get ( ActiveFieldContents ) will work, more or less
For example, you can set a script attached to a button on the portal row (or make the field(s) themselves on the row the button) so that when you click on it you trap as variables any of the related values you want. They don't even have to be any of the values displayed in the portal row.
So the script might look like:
Set Variable ($StartDate ; PortalRelationship::StartDate )
Set Variable ($StartDate ; PortalRelationship::EndDate )
Set Variable ($StartDate ; PortalRelationship::Description )
You can then do with those trapped values whatever you like.
works perfectly, simple as it should be. i must be asking google the wrong questions, i could not find this info.
