Ok so, im making a defense boost tool thing, in studio it works just fine but in game it breaks.

active = false
defenseMode = false
db = false
local char = game.Workspace:WaitForChild(script.Parent.Parent.Parent.Name)


script.Parent.Activated:Connect(function()
	 previousHealth = char.Humanoid.Health
	if active == false and defenseMode == false then
		print("xd")
		active = true
		defenseMode = true
		wait(5)
		defenseMode = false
		wait(30)
		active = false
	end
end)	    function onChanged()
		local Diffirence = tonumber(previousHealth) - char.Humanoid.Health
		if defenseMode == true then
			local GetPercent = 0
			local Part1 = Diffirence / 2
			print(Part1)
			local Part2 = Part1 / 2
			print(Part2)
			GetPercent = Part1 + Part2
			print(GetPercent)
			char.Humanoid.Health = char.Humanoid.Health + GetPercent
				GetPercent = 0
			end
		end
char.Humanoid:GetPropertyChangedSignal("Health"):Connect(function()
		if db == false then
			db = true
			onChanged()
			wait()
			db = true
		end
	end)
