Taking Controls from two people

I'm having a problem with controls. The vehicle is a two seater, with two separate scripts in two separate seats (one driver, one gunner).

Each script takes controls from the person sitting in it.

The problem is the gunner's controls and the driver's controls are getting mixed up, the gunner is also driving, even though that's in a separate script that never got controls from him.

Does anyone know why this is?

I can only assume because the driver seat is the root prim or something?

Aaanyways, if it isn't that, run a detection test on the control input, so whilest it reads controls from both it only actually listens to the right one.

the control event return you the key of the controlled person , use it as a filter
