Second Generation Sim Mechanics Motion Actuation

I'm trying to actuate a prismatic joint to follow a specific motion. I basically want the joint motion to be sinusoidal in the vertical direction. In the prismatic joint dialogue box, I've selected "Provided by Input" under the Actuation >> Motion drop-down menu. Then I have a sine source going through a 3-input Mux (for position, velocity, and acceleration) through a Simulink-PS converter to the Prismatic Joint input. This arrangement isn't working, and I've tried several other arrangements that have failed. I'm sure there is a way to do it, but I haven't had any luck. Any advice would be greatly appreciated.

Again, I'm using the second generation of sim mechanics.

Sicne you don't provide the error, it is difficult to diagnose... The "Joint Actuation" doc page explains what you need to actuate a joint in motion:
