Is my script wrote correctly?

my script does not seem to work right for some reason why??

This is the script

-- Made By RainbowBeastYT


local tool = script.Parent

local speedboost =1.25

local handle = tool:WaitForChild("Handle")
local event = tool:WaitForChild("RemoteEvent")
local damage = 100
local lastclick = tick()
local swingtime = 1
local combowindow = .5
local combo = 0

local equipped = true
local character = tool.Parent
local player = game.Players:GetPlayerFromCharacter(character)
local humanoid = character:FindFirstChild("Humanoid")
local hithumanoid = {}

	

tool.Equipped:Connect(function()
	lastclick = tick()
	combo = 0
	if humanoid then
		humanoid.Walkspeed = humanoid.Walkspeed * speedboost
	else
		character = nil
	end
end)

tool.Unequipped:Connect(function()
	if humanoid then
		humanoid.Walkspeed = humanoid.Walkspeed / speedboost
	end
	character = nil
	humanoid = nil
end)


handle.Touched:Connect(function(hit)
	if equipped and character and humanoid and humanoid.health > 0 and hit and not hit:isDescendantOf(character) then
		local targethumanoid = hit.Parent:FindFirstChild("Humanoid")
		if targethumanoid and targethumanoid.Health > 0 and not hithumanoid(targethumanoid) then
			hithumanoid[targethumanoid] = true
			targethumanoid:TakeDamage(damage * combo)
		end
	end
end)

tool.Activated:Connect(function()
	local clickdelta = tick() - lastclick
	if clickdelta > swingtime then
	lastclick = tick()
	local hithumanoid = {}
	if clickdelta < swingtime + combowindow then
		combo = (combo + 1) % 3
	else
		combo = 0
	end
	if player then
		if combo == 0 then
			event:FireClient(player, "RunAnimation", "DownStab")
			script.Parent.Handle.Swoosh:Play()
		elseif combo == 1 then
			event:FireClient(player, "RunAnimation", "StabPunch")
			script.Parent.Handle.Swoosh1:Play()
		elseif combo == 2 then
			event:FireClient(player, "RunAnimation", "ThrowCharge")
			script.Parent.Handle.Ting:Play()
			end
		end
	end
end)
