Get and Set a MPC Vector at each frame ?

I am struggling with this, I need the Set Vector Parameter to be at each frame, but it only works with the Event BeginPlay and I don’t understand why.
Can anyone explain?

Maybe the blueprint is not ticking? Check in the class defaults. Or you know, the mother of all debuggers - Print String.

Thanks. It was indeed not ticking, lol.
