Creating a pickup item

I'm trying to create a pickup item (like the healthKit), but I'm having problems getting it to show up in the "Shapes" directory.

I've created a .dsq & .dts file and moved them to a created folder:
example\starter.fps\data\shapes\pickups

I've also duplicated health.cs found in example\starter.fps\server\scripts
renamed it to pickups.cs and edited it to use my .dts:

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

   // Basic Item properties
   shapeFile = "~/data/shapes/pickups/pickup_wpn_axe.dts";
   mass = 1;
   friction = 1;
   elasticity = 0.3;
   emap = true;

   // Dynamic properties defined by the scripts
   pickupName = "my test pickup";
   repairAmount = 50;
};

Lastly, I've added this line to server/scripts/game.cs

exec("./pickups.cs");

Am I missing anything? Much thanks!
