Knife throw script not working?

Edited 4 years ago

So I'm currently making a throwing knife script but when the remote server is fired an error popped up saying 20:06:36.909 - ServerScriptService.The World.Knife Throw:24: attempt to perform arithmetic (mul) on nil and number

There's a local script and a normal script

local script

01local plr = game:GetService("Players").LocalPlayer
02 
03local rp = game:GetService("ReplicatedStorage")
04local KnifeThrow = rp:WaitForChild("The World:Remotes"):WaitForChild("KnifeThrow")
05 
06local UIS = game:GetService("UserInputService")
07 
08local debounce = false
09local cooldown = 0.75
10 
11 
12UIS.InputBegan:Connect(function(input,IsTyping)
13   if IsTyping then
14      return
15   elseif input.KeyCode == Enum.KeyCode.T then     
16      if workspace:FindFirstChild(plr.Name.." Barrage") then
17         return
18      else
19         if debounce == false then
20            debounce = true
21 
22            local Character = plr.Character
23            local Humanoid = Character:WaitForChild("Humanoid")
24 
25            local pos = Character.Humanoid.TargetPoint
26            local LookAt = (pos - Character.Head.Position).Unit
27            KnifeThrow:FireServer()
28            wait(cooldown)
29            debounce = false
30         end
31      end
32   end
33end)

Normal script

01local rp = game:GetService("ReplicatedStorage")
02local knife = rp:WaitForChild("The World:Remotes"):WaitForChild("KnifeThrow")
03local Debris = game:GetService("Debris")
04 
05local TweenService = game:GetService("TweenService")
06 
07local damage = 6.25
08 
09knife.OnServerEvent:Connect(function(Player,LookAt)
10   local Character = Player.Character
11   local Humanoid = Character:WaitForChild("Humanoid")
12   local HumanoidRP = Character:WaitForChild("HumanoidRootPart")
13 
14   local thr = Humanoid:LoadAnimation(script:WaitForChild("Throw"))
15   thr:Play()
16 
17   local Folder = Instance.new("Folder",workspace)
18   Folder.Name = Player.Name.." Knives"
19 
20   for i = 1, 3 do
21      local knife0 = script.Knife:Clone()
22      knife0.CFrame = Character:WaitForChild("Right Arm").CFrame
23      knife0.Parent = Folder
24      knife0.Velocity = LookAt * 30
25      local fly = Instance.new("BodyForce",knife0)
26      fly.Force = Vector3.new(0,knife0:GetMass()*196.2,0)
27      game.Debris:AddItem(knife0,10)
28      wait()
29      knife0.Touched:Connect(function()
30         wait(15)
31         knife0:remove()
32      end)
33   end
34end)
