My script that makes a NPC attack is crashing?

I am using a script to make the NPC attack the player. And it is currently not working. I don't know why because I am a fairly new scripter. ``` local larm = script.Parent:FindFirstChild("Left Arm") local rarm = script.Parent:FindFirstChild("Right Arm")

function findNearestTorso(pos) local list = game.Players:GetPlayers() local torso = nil local dist = 10 local temp = nil local human = nil local temp2 = nil for x = 1, #list do temp2 = list[x] if temp2.Character:IsA("Model") then temp = temp2.Character:FindFirstChild("Torso") human = temp2.Character:FindFirstChild("Humanoid") if (temp ~= nil) and (human ~= nil) and (human.Health > 0) then if (temp.Position - pos).magnitude < dist then torso = temp dist = (temp.Position - pos).magnitude end end end end return torso end

while true do wait(0.1) local target = findNearestTorso(script.Parent.Torso.Position) if target ~= nil then script.Parent.Humanoid:MoveTo(target.Position, target) end end That is my first script which I placed in the humanoid section and it keeps. My damage script is below script.Parent.Touched:connect(function(part) if part.Parent:FindFirstChild("Humanoid") then part.Parent.Humanoid:TakeDamage(30) end) ```
