Iv'e already made a script but it's not working for r15. can someone fix this please?

game.Players.PlayerAdded:connect(function(plr) plr.CharacterAdded:connect(function(char) Delay(1, function() local stuff = char:GetChildren()

    for i = 1,#stuff do
        if stuff[i].ClassName=="Hat" or stuff[i].ClassName == "ShirtGraphic" or stuff[i].ClassName=="Pants" or stuff[i].ClassName == "Shirt" or stuff[i].ClassName == "BodyColors" or stuff[i].ClassName == "CharacterMesh" then
        stuff[i]:Remove()
        end
    end
    local stuff1 = char.Torso:GetChildren()
    for i = 1,#stuff1 do
        if stuff1[i].ClassName=="Decal" then
            stuff1[i]:Remove()
        end
    end


    local shirts = game.ServerStorage.Uniform.Shirts:GetChildren()
    if #shirts >0 then
    local i = math.random(1,#shirts)
    shirts[i]:Clone().Parent=char
    end

    local Pants = game.ServerStorage.Uniform.Pants:GetChildren()
    if #Pants >0 then
    local i = math.random (1,#Pants)
    Pants[i]:Clone().Parent=char
    end     

    local bodycolor = game.ServerStorage.Uniform.BodyColors:GetChildren()
    if #bodycolor >0 then
    local i = math.random(1,#bodycolor)

    char:FindFirstChild("Head").BrickColor = bodycolor[i].Value
    char:FindFirstChild("UpperTorso").BrickColor = bodycolor[i].Value
    char:FindFirstChild("LowerTorso").BrickColor = bodycolor[i].Value
    char:FindFirstChild("LeftUpperArm").BrickColor = bodycolor[i].Value
    char:FindFirstChild("LeftLowerArm").BrickColor = bodycolor[i].Value
    char:FindFirstChild("LeftHand").BrickColor = bodycolor[i].Value 
    char:FindFirstChild("RightUpperArm").BrickColor = bodycolor[i].Value
    char:FindFirstChild("RightLowerArm").BrickColor = bodycolor[i].Value
    char:FindFirstChild("RightHand").BrickColor = bodycolor[i].Value
    char:FindFirstChild("LeftUpperLeg").BrickColor = bodycolor[i].Value

    char:FindFirstChild("RightFoot").BrickColor = bodycolor[i].Value
    end

    local faces = game.ServerStorage.Uniform.Faces:GetChildren()
    if #faces > 0 then
    local stuff2 = char.Head:GetChildren()
    for i =1,#stuff2 do
        if stuff2[i].ClassName=="Decal" then
            stuff2[i]:Remove()
        end
    end

    local i = math.random(1,#faces)
    faces[i]:Clone().Parent=char.Head   
    end

    local packages = game.ServerStorage.Uniform.Package:GetChildren()
    if #packages > 0 then
    local i = math.random (1,#packages)
    local stuff3 = packages[i]:GetChildren()
    for i = 1, #stuff3 do
        stuff3[i]:Clone().Parent=char
    end
    end
