Update Record using Related Action in a Record View

I'm trying what should be a very simple task ... and I can't get it working!  I've created a Related Action to update a record - just used the automatic creation tool that built me an interface and a process.  In my user interface, if I include the related actions dropdown on the record view, this update works perfectly. The interface shows all the fields and allows me to update and hit Save. Perfect.

But now instead of using that interface from the related action dropdown, i'd like to place it in a view so that it shows as a toolbar menu item across the top toolbar. But now, when I hit Save on that interface, nothing happens. It's like it's not calling the process at all. 

Here's my related action and my view - what am I missing?
