Dynamic Picking Error from a form in a collapse card

I was setting a dynamic dropdown select (filtering the second table with the value of the first select field).

It wasn’t working (like it had in the past): here’s what I learned…

When I used the value created by the dynamic data picker dmx-param:filter="card1_collapse.staffUpdate.tempLocation.value" the second dropdown did not filter on the value. When I manually removed the card1_collapse. portion of the element, the proper data was populated in my second select box.
