and also if you can help me with this but that you need me to replace somethings differently so it works you can also tell me

function onTouched(hit)
    if hit.Parent:findFirstChild("Humanoid") ~= nil and hit.Parent:findFirstChild("Chest") == nil then
        local g = script.Parent.Parent.Chest:clone()
        g.Parent = hit.Parent
        local C = g:GetChildren()
        for i=1, #C do
            if C[i].className == "Part" or C[i].className == "UnionOperation" or C[i].className == "WedgePart" then
                local W = Instance.new("Weld")
                W.Part0 = g.Middle
                W.Part1 = C[i]
                local CJ = CFrame.new(g.Middle.Position)
                local C0 = g.Middle.CFrame:inverse()*CJ
                local C1 = C[i].CFrame:inverse()*CJ
                W.C0 = C0
                W.C1 = C1
                W.Parent = g.Middle
            end
                local Y = Instance.new("Weld")
                Y.Part0 = hit.Parent.Torso
                Y.Part1 = g.Middle
                Y.C0 = CFrame.new(0, 0, 0)
                Y.Parent = Y.Part0
        end

        local h = g:GetChildren()
        for i = 1, # h do
            if h[i].className == "Part" or  h[i].className == "UnionOperation" or C[i].className == "WedgePart" then  
                h[i].Anchored = false
                h[i].CanCollide = false
            end
        end

    end
end

script.Parent.Touched:connect(onTouched)

this is the script called Torso and I don't know how to make it work do that when I click the model in Monster Called (Chest) changes the torso of the character into the chest model
