my sword doesnt moves at all, thats the code:

local debounce = false
local ragdoll = require(game.ServerScriptService.Ragdoll)
local function attack(plr)
	for i,v in pairs(workspace:GetChildren()) do
		if v.Name ~= plr.Character.Name then
			if v:FindFirstChild("Humanoid") then
				if (plr.Character.Torso.Position - v.Torso.Position).Magnitude < 15 then
					if not v:FindFirstChild("counter") then
							local huumanE = v.Humanoid
							huumanE:TakeDamage(7)
							local hit = Instance.new("BoolValue",v)
							hit.Name = "Hit"
							huumanE.WalkSpeed = 1
							game.Debris:AddItem(hit,1)
							return v
					else
						plr.Character.Humanoid.WalkSpeed = 0
						local hit = Instance.new("BoolValue",plr.Character)
						hit.Name = "Hit"
						local anim = plr.Character.Humanoid:LoadAnimation(script.GetCounter)
						anim:Play()
						for i,v in pairs(v.Humanoid:GetPlayingAnimationTracks()) do
							v:Stop()
						end
						v.counter.Value = true
						v.counter:Destroy()
						wait(2)
						hit:Destroy()
						plr.Character.Humanoid.WalkSpeed = 16
					end
				end
			end
		end
	end
end

script.Parent.OnServerEvent:Connect(function(plr)
	if debounce == false then
		if not plr.Character:FindFirstChild("Hit") then
			script.Parent.Parent.Parent.Handle.Trail.Enabled = true
			local humanF = plr.Character.Humanoid
				script.Parent.Parent.Parent.Handle["Slash 4"]:Play()
				local hit = Instance.new("BoolValue",plr.Character)
				hit.Name = "Hit"
				local anim = humanF:LoadAnimation(script.Swing1)
			anim:Play()
			wait(.5)
				local char = attack(plr)
			if char then
				local bv = Instance.new("BodyVelocity",char.HumanoidRootPart)
				bv.MaxForce = Vector3.new(math.huge,math.huge,math.huge)
				bv.Velocity = plr.Character.HumanoidRootPart.CFrame.lookVector * 50
				local par = script.Blood:Clone()
				par.Parent = char.Torso
				par:Emit(500)
				game.Debris:AddItem(par,2)
				game.Debris:AddItem(bv,2)
				ragdoll(char,2)
				char.Humanoid.WalkSpeed = 16
			end
			wait(.5)
			script.Parent.Parent.Parent.Handle.Trail.Enabled = false
				hit:Destroy()
			
		end
	end
end)
