Why is Clothing a nil value?

For some reason, whenever this script fires , Clothing comes back as nil. Everything is where it should be and spelled right..Thanks for any help.

local co = game.Lighting.OutfitStorage.Helmets

function WeldHelmet()

local PlayerAttire = player.PlayerGui:FindFirstChild("Outfit")
local Clothing = co:FindFirstChild(PlayerAttire.OutfitHelmet.Value)
    local char = player.Character or player.CharacterAdded:wait()
    local OutfitTop = Clothing:Clone()
    OutfitTop.Parent = game.Workspace

    for _,v in pairs(OutfitTop:GetChildren()) do
        if v.ClassName == "Part" or v.ClassName == "UnionOperation" then
            v.Anchored = true
        end
    end

    OutfitTop.Parent = workspace

    for _,v in pairs(OutfitTop:GetChildren()) do
        if v.ClassName == "Part" or v.ClassName == "UnionOperation" then
            if v ~= OutfitTop["HelmetCore"] then
                weld(v, OutfitTop["HelmetCore"])
            end
        end
    end

    local OutfitTopWeld = weld(OutfitTop["HelmetCore"], char["FakeHead"], CFrame.new())

    for _,v in pairs(OutfitTop:GetChildren()) do
        if v.ClassName == "Part" or v.ClassName == "UnionOperation" then
            v.Anchored = false
            v.CanCollide = false
        end
    end

end
