How to check if a certain item is the child of an object before initiating a script?

I have a morph I am building, which is supposed to include parts which will change transparency, but I need to write a script which makes sure that there is only one 'chest' model which is child to the character in order for it to work properly. I have tried to write a script which is meant to check if there is already a 'chest' model child to the character before continuing with the rest of the script, and it went something like this:

local found = game.Players.Player.Character:FindFirstChild("Chest") local Morph = script.Parent.Parent["Chest"]

if found == false then

function Check(plr)
local ToReturn = true
return ToReturn

end

function GiveMorph(plr) coroutine.resume(coroutine.create(function() if plr.Character:FindFirstChild(Morph.Name) == nil then if Check(plr) == true then wait(0.1) local Cloned = Morph:clone() Cloned.Parent = plr.Character for i, v in pairs(Cloned:GetChildren()) do coroutine.resume(coroutine.create(function() if v:IsA("BasePart") then if v.Name ~= "Middle" then local w = Instance.new("Weld") w.Part0 = Cloned["Middle"] w.Part1 = v w.C0 = w.Part0.CFrame:inverse() * CFrame.new(w.Part1.Position) w.C1 = w.Part1.CFrame:inverse() * CFrame.new(w.Part1.Position) w.Parent = w.Part0 else coroutine.resume(coroutine.create(function() wait(0.1) local w = Instance.new("Weld", plr.Character["Torso"]) w.Part0 = plr.Character["Torso"] w.Part1 = v w.C0 = CFrame.new(0, 0, 0) end)) end end end)) end for i, v in pairs(Cloned:GetChildren()) do coroutine.resume(coroutine.create(function() if v:IsA("BasePart") then v.Anchored = false v.CanCollide = false end end)) end if plr.Character:findFirstChild("Shirt") ~= nil then plr.Character["Shirt"]:remove() end if script.Parent:findFirstChild("Shirt") ~= nil then script.Parent["Shirt"]:clone().Parent = plr.Character end if plr.Character:findFirstChild("Pants") ~= nil then plr.Character["Pants"]:remove() end if script.Parent:findFirstChild("Pants") ~= nil then script.Parent["Pants"]:clone().Parent = plr.Character end for i, v in pairs(plr.Character:GetChildren()) do coroutine.resume(coroutine.create(function() if v:IsA("CharacterMesh") then v:remove() end if v:IsA("Hat") then v:remove() end end)) end end end end)) end

function Touch(hit) coroutine.resume(coroutine.create(function() if hit.Parent:findFirstChild("Humanoid") ~= nil then local plr = game.Players:GetPlayerFromCharacter(hit.Parent) if plr ~= nil then GiveMorph(plr) wait(5) end end end)) end

script.Parent.Touched:connect(Touch)

• note that the very beginning of the script in regards to 'found' and 'if found == false then' are the parts which are supposed to check if the 'chest' part is child to the character. It hasn't worked for me so for, so what am I doing wrong?

local found = game.Players.LocalPlayer.Character:FindFirstChild("Chest") --If you are looking for the torso part, change this to "Torso"

if found ~= nil then
	print("Hello, World!")
	--Other code needed
end
