How would i fix Gui that breaks on reset?

The Variables would print

but the objects wont appear and change the players name

local plr = game.Players.LocalPlayer
local char = plr.Character or plr.CharacterAdded:wait()
local backpack = plr.Backpack
local light = game.Lighting

local deb = false
script.Parent.FocusLost:connect(function(a)
	if deb then return end
	deb = true
	print ' deb is true'
	if a then
		local nt = char:GetChildren()--Finds if theres one already existing
		for a, ta in pairs(char:GetChildren()) do
			if ta:findFirstChild('Name') then
				ta:Destroy()
				char.Head.Transparency = 0
				print 'found a model'
			end
		end
	end
	
	
	local ta = Instance.new("Model", char)
	ta.Name = script.Parent.Text.. " : " ..plr.Name
	local ch = char.Head:Clone()
	ch.Parent = ta
	print 'made a new model and heal'
	
	local human = Instance.new("Humanoid", ta)
	human.Name = "Name"
	print 'new humanoid'
	
	
	local w = Instance.new("Weld", ch)
	w.Part0 = ch 
	w.Part1 = char.Head
	char.Head.Transparency = 1
	print 'new weld'
	
	wait(5)
	deb = false
	print ' done'
	
	
end)
