Case is not a valid member of Model "tumtindy.Case". Whats happening?

Case is not a valid member of Model "tumtindy.Case" is my error,

I am pretty new to scripting, so this might be an obvious mistake but for me it is not. I am trying to make my model called "Sword" be visible inside of my "Case" which is attached to the HumanoidRootPart. (This is for R6)

game.Players.PlayerAdded:Connect(function(player)
	player.CharacterAdded:Connect(function(Character)
		local Case = script.Case:Clone()
		Case:SetPrimaryPartCFrame(Character.HumanoidRootPart.CFrame)
		Case.Parent = Character
		
		local weld = Instance.new("ManualWeld")
		weld.Part0 = Case.PrimaryPart
		weld.Part1 = Character.PrimaryPart
		weld.C0 = weld.Part0.CFrame:ToObjectSpace(weld.Part1.CFrame)
		weld.Parent = weld.Part0
		
		local Sword = script.Sword:Clone()
		Sword:SetPrimaryPartCFrame(Case.Case.CFrame * CFrame.new(0,0,-4))
		Sword.Parent = Character
		
		local weld2 = Instance.new("ManualWeld")
		weld2.Part0 = Sword.PrimaryPart
		weld2.Part1 = Case.PrimaryPart
		weld2.C0 = weld2.Part0.CFrame:ToObjectSpace(weld2.Part1.CFrame)
		weld2.Parent = weld2.Part0
	end)
end)

Make sure Case exist and didn't get destroyed on run time

The problem is very simple, try this one. Well I'm not sure cause I don't know where you really want to place the case or which line break cause you didn't include that.

game.Players.PlayerAdded:Connect(function(player)
    player.CharacterAdded:Connect(function(Character)
        local Case = script.Case:Clone()
        Case:SetPrimaryPartCFrame(Character.HumanoidRootPart.CFrame)
        Case.Parent = Character.HumanoidRootPart

        local weld = Instance.new("ManualWeld")
        weld.Part0 = Case.PrimaryPart
        weld.Part1 = Character.PrimaryPart
        weld.C0 = weld.Part0.CFrame:ToObjectSpace(weld.Part1.CFrame)
        weld.Parent = weld.Part0

        local Sword = script.Sword:Clone()
        Sword:SetPrimaryPartCFrame(Case.Case.CFrame * CFrame.new(0,0,-4))
        Sword.Parent = Character

        local weld2 = Instance.new("ManualWeld")
        weld2.Part0 = Sword.PrimaryPart
        weld2.Part1 = Case.PrimaryPart
        weld2.C0 = weld2.Part0.CFrame:ToObjectSpace(weld2.Part1.CFrame)
        weld2.Parent = weld2.Part0
    end)
end)
