Hi,
it's likely a problem of Incontrol setup, the playmaker actions only get the result of InControl.
I would ask the contributor to provide a working scene or something, just to verify that a regular scene works, and then you try to hook up on that scene to catch the same input. That's how I proceed myself when troubleshooting and I am not sure where the issue is, you need to rule out PlayMaker first.
Bye,
Jean
