I have an Edit View, let's call it "Maintenance-Edit" that I'm opening via a ViewLink from a ListView called "Equipment-List" to add new maintenance records for that piece of equipment. On the Maintenance-Edit form, i have an Embedded View of a List View called "Maintenance-List" that has all records from the maintenance table. I want to filter that List View to only show records for the same EquipmentID as the Piece of equipment I'm adding.

I've tried to do this via the "Extra state Formula" on the List View, but I can't figure out the forumula. 

I'd truly appreciate some help.
