Picking up items

I'm trying to add power bars to my game which, when you run over them, will add to the players energy and allow them to run.

I modeled my little bouncing powerbar in max and I added a sequence. Then I opened up health.cs and copied the health kit code and renamed everything PowerBar. Then I added code to animate the sequence all the time.

Now the problem is, in the game I can run over health kits just fine, but when I put down my powerbar, nothing happens. It just sits there spinning and I can't pick it up. What am I doing wrong?

Here is the code I have in health.cs

datablock ItemData(PowerBar)
{
   // Mission editor category, this datablock will show up in the
   // specified category under the "shapes" root category.
   category = "Energy";

   // Basic Item properties
   shapeFile = "~/data/shapes/items/powerbar.dts";
   mass = 1;
   friction = 1;
   elasticity = 0.3;

   // Dynamic properties defined by the scripts
   pickupName = "a powerbar";
   repairAmount = 50;
};

function PowerBar::onUse(%this,%user)
{
   // Apply some health to whoever uses it, the health kit is only
   // used if the user is currently damaged.
   if (%user.getDamageLevel() != 0) {
      %user.decInventory(%this,1);
      %user.applyRepair(%this.repairAmount);
      if (%user.client)
         messageClient(%user.client, 'MsgHealthKitUsed', '\c2You ate the power bar');
   }
}

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