sling = script.Parent:WaitForChild('Slingshot')

function Reload()
	if ammo.Value == 0 and storedammo.Value > 0 then
		ammo.Value = ammo.Value + 1
		storedammo.Value = storedammo.Value - 1
elseif
		storedammo.Value == 0 and ammo.Value == 0 then
		print('Out of Ammo!')
		ammo.Value = ammo.Value
	end
end

function Check()
	if ammo.Value == 0 and storedammo.Value == 0 then
		sling.Disabled = true
elseif
		ammo.Value > 0 or storedammo > 0 then
		sling.Disabled = false
	end
