Ammo in Editor?

I built a pistol and did the basic change over from the rifle to the pistol(script). Everything works except the ammo. I have the datablock in my script but for some reason it won't show up in the world editor.
This is the code that comes out of the Pistol.cs file for the ammo.

// Ammo Item

datablock ItemData(pistolAmmo)
{
   // Mission editor category
   category = "Ammo";

   // Add the Ammo namespace as a parent.  The ammo namespace provides
   // common ammo related functions and hooks into the inventory system.
   className = "Ammo";

   // Basic Item properties
   shapeFile = "~/data/shapes/pistol/ammo.dts";
   mass = 1;
   elasticity = 0.2;
   friction = 0.6;

	// Dynamic properties defined by the scripts
	pickUpName = "pistol ammo";
   maxInventory = 50;
};

pretty just like the rifle in fact I am using the same model and all for TEMP. Is there another script I need to reference the AMMO. The gun loads and works So as far as the "Game.cs","Config.cs"and the "defaultbind.cs" I thought I did everything right?
Any help is appriciated.
