there seems to be an adding problem?

For a random reason, the ammo it supposed to be adding per touch seems to add the original stored amount of ammo along with the refill amount. the ammo box script and gun script is here:

--ammobox script
function onTouched(hit) 
if (hit.Parent:FindFirstChild("Humanoid") ~= nil) then
local d = hit.Parent:GetChildren()
for i=1, #d do 
if (d[i].className == "Tool") then
print(d[i].StoredAmmo.Value)
d[i].StoredAmmo.Value = d[i].StoredAmmo.Value + d[i].RefillAmount.Value
script.Parent.AmmoLeft.Value = script.Parent.AmmoLeft.Value - d[i].RefillAmount.Value
d[i].Parent.Humanoid.Health = d[i].Parent.Humanoid.MaxHealth
script.Sound:Play()
print(d[i].StoredAmmo.Value)
script.Disabled = true
wait(1)
script.Disabled = false
end 
end
end
end 

script.Parent.Touched:connect(onTouched)

gun script

local tool = script.Parent
local player = game:GetService("Players").LocalPlayer
local gunIsFiring = false
local enabled = false
local on = false
tool.Equipped:connect(function(mouse)
function onKeyPressR(inputObject, gameProcessedEvent)
	if inputObject.KeyCode == Enum.KeyCode.R then
		if script.Parent.Ammo.Value == 0 and script.Parent.StoredAmmo.Value > 0 and enabled == true and gunIsFiring == false and on == true then 
		
        script.Parent.Ammo.Value = script.Parent.Ammo.Value + script.Parent.MaxAmmo.Value
        script.Parent.StoredAmmo.Value = script.Parent.StoredAmmo.Value - script.Parent.MaxAmmo.Value
        tool.Handle.ReloadSound:Play()
print(script.Parent.StoredAmmo.Value)
wait(1.4)	
on = false
enabled = false
	end
		

		end
	end
	
-- below here is irrelevant since it only deals with firing the gun
	mouse.Button1Down:connect(function()
		
		if script.Parent.Ammo.Value > 0 and enabled == false then
		gunIsFiring = true
			script.Parent.Ammo.Value = script.Parent.Ammo.Value - 1
		local ray = Ray.new(tool.Handle.CFrame.p, (mouse.Hit.p + Vector3.new(math.random(-100,100)*0.01,0,0) - tool.Handle.CFrame.p).unit * 300)
		local part, position = workspace:FindPartOnRay(ray, player.Character, false, true)
 
		local beam = Instance.new("Part", workspace)
		beam.BrickColor = player.TeamColor
		beam.FormFactor = "Custom"
		beam.Material = "Neon"
		beam.Transparency = 0.25
		beam.Anchored = true
		beam.Locked = true
		beam.CanCollide = false
        tool.Handle.FireSound:Play()
		local distance = (tool.Hole.CFrame.p - position).magnitude
		beam.Size = Vector3.new(0.2, 0.2, distance)
		beam.CFrame = CFrame.new(tool.Hole.CFrame.p, position) * CFrame.new(0, 0, -distance / 2)
 
		game:GetService("Debris"):AddItem(beam, 0.1)
 
		if part then
			local humanoid = part.Parent:FindFirstChild("Humanoid")
 
			if not humanoid then
				humanoid = part.Parent.Parent:FindFirstChild("Humanoid")
			end
 
			if humanoid then
				humanoid:TakeDamage(20)
			
				
			end
		end
		end
		if script.Parent.Ammo.Value == 0 and enabled == false then
			gunIsFiring = false
			enabled = true
			on = true
	end
	end)
	game:GetService("UserInputService").InputBegan:connect(onKeyPressR)
end)

The output from the gun says the value of the stored ammo is what i want it to be. Whereas, the output from the ammo box says the original ammo amount + the refill amount I want. If there is something unclear, comment what is unclear before down voting.
