Mount and Unmount from Chair Problems

Problem is I've forgotten the difference between variable types in T3D. I'm thinking that's why the player will mount, but won't unmount.

Also, is mountPose the proper way to play an animation on a non-vehicle shape?

Shape's script:

datablock StaticShapeData(RockingChair)
{ 
	shapeFile = "art/shapes/RockingChair/RockingChair.dae";
	category = "AnimatedObjects";
	className = "RockingChair";
	mountable = true;
	mountPoint = 0;
	numMountPoints = 1;
	mountPose[0] = sitting;
};

function RockingChair::onAdd(%this,%obj)
{
   %obj.playThread(0,"ambient");   
}

Server script:

function RockingChair::onCollision(%this, %obj, %col)
{
   if (%col.getState() !$= "Dead")
   {
      warn("Rocking Chair Collision");
	  %obj.mountObject(%col, 0);
	  %this.schedule(3000, unmount);
   }
   
}

function RockingChair::unmount(%this, %obj, %col)
{
	warn("Player unmount");
	%obj.unmountObject(%col);
	%col.setTransform(%spawnPoint);
}

Thanks!
