Can't figure it out.

AddCSLuaFile( "cl_init.lua" ) // Make sure clientside  
AddCSLuaFile( "shared.lua" )  // and shared scripts are sent.

function ENT:Initialize()     	
	self.Entity:SetModel( "models/items/ammocrate_smg1.mdl" )  	
	self.Entity:PhysicsInit( SOLID_VPHYSICS )      // Make us work with physics,  	
	self.Entity:SetMoveType( MOVETYPE_VPHYSICS )   // after all, gmod is a physics  	
	self.Entity:SetSolid( SOLID_VPHYSICS )         // Toolbox                
	local phys = self.Entity:GetPhysicsObject()  	
	if (phys:IsValid()) then  		
		phys:Wake()  	
	end  
	self.use = false

end     


function ENT:SpawnFunction( ply, tr )

	if ( !tr.Hit ) then return end

	local SpawnPos = tr.HitPos + tr.HitNormal * 16

	local ent = ents.Create( "sent_AmmoCrate" )
	ent:SetPos( SpawnPos )
	ent:Spawn()
	ent:Activate()
	return ent
end



function ENT:Use(activator)
if (self.use) and (activator:IsAdmin()) then
activator:GiveAmmo( 500, "SMG1" )
activator:GiveAmmo( 500, "Pistol" )
activator:GiveAmmo( 500, "Buckshot" )
self.use = false
timer.Simple(0.1,usereply,self)
end
end

function usereply(self)
self.use = false
end

It doesn't work.... At all, it can only spawn... also I want it to be able to be used by anyone, but I cannot figure it out.
Its a simple ammo crate that I can't seam to get working.

Then take steps back in your code. Take out the if statments in your use function and throw in a print("Testing") to debug if its working or not. It will print Testing in your console when you do the use on it if it works.
