Backpack Accessory

Trying to make a backpack that both appears on your back and operates as extra storage like a boxed backpack, however I'm having an issue. The item does not appear in the inventory of the person given it.

local ITEM = Clockwork.item:New();
ITEM.name = "10L Backpack";
ITEM.model = "models/fallout 3/backpack_1.mdl";
ITEM.weight = 1;
ITEM.category = "Storage";
ITEM.isRareItem = true;
ITEM.description = "A small backpack that will only hold ten litres.";
ITEM.addInvSpace = 5;
ITEM.useText = "Wear";
ITEM.uniqueID = "backpack_10l"

ITEM.isAttachment = true;
ITEM.attachmentBone = "ValveBiped.Bip01_Spine";
ITEM.attachmentOffsetAngles = Angle(0, 0, 0);
ITEM.attachmentOffsetVector = Vector(-2, 0, 0);

		Clockwork.player:Notify(player, "You can only wear one backpack at a time!");
			
		return false;
	end;
	
	player:GiveItem(Clockwork.item:CreateInstance("backpack_10l"));
end;

			target:GetInventory()
		);

		if (inventoryWeight > (target:GetMaxWeight() - self("addInvSpace"))) then
			return false;
		end;
	end;

		return false;
	end;
end;

ITEM:Register();

Thanks!

 

Here this should fix it Click here Btw mind if I steal this idea and make it a plugin?

 

-SNIP-
I DUN GOOFED

 

These are for WARPAC, so I'd prefer if it wasn't widely used before launch.

Thank you for the fix however. I'll try it once I'm home and let you know if it works.
