Why doesnt the :Clone() work in starter Character (with script)?

Any help is really appreciated should be simple (I think) everything included below script.

--Variables.
	wait()
	local Character1 = script.Parent
	local d20Roler1 = script:FindFirstChild("BillBoardGuiSyn")
	 
	 
	local d20Clone = d20Roler1:Clone()
	d20Clone.Parent = Character1:FindFirstChild("Head")
	d20Clone.Adornee = Character1:FindFirstChild("Head")
	d20Clone.Frame.TextLabelSyn = Character1.Name

The problem is on line four and it says (error): https://gyazo.com/76781df5d397ad7f1ee0c27d8b28e995

Heres the hierarchy: https://gyazo.com/3ecae62ee37f5e4a3a2cb61cb0768a15

This is because the script does not have a child on line 4 that is named "BillBoardGuiSyn". You are using find first child, and it does not see that child. this is a simple fix :

--Variables.
    wait()
    local Character1 = script.Parent
    local d20Roler1 = workspace.Part:FindFirstChild("BillBoardGuiSyn")


    local d20Clone = d20Roler1:Clone()
    d20Clone.Parent = Character1:FindFirstChild("Head")
    d20Clone.Adornee = Character1:FindFirstChild("Head")
    d20Clone.Frame.TextLabelSyn.Text = Character1.Name
