How to make a respawn countdown gui?

Hello, i want to make a respawn countdown gui, but im new when it comes to scripting. I made this so far:

local rDelay = 5

function tp()
	txt = game.StarterGui.ScreenGui.TextLabel
	txt.TextTransparency = 0
	txt.TextStrokeTransparency = 0
	txt.Position = {0,0},{0,0}
	txt.Text = "Respawning in:"..tostring(rDelay)
	wait(5)
	txt.TextTransparency = 1
	txt.TextStrokeTransparency = 1
	txt.Position = {1,0},{1,0}
	target = Cframe.new(0,50,0)
	hoomanoid = character:FindFirstChild("Torso")
	hoomanoid.Cframe = target + Vector3.new(0,50,0)
end
local humanoid = character:FindFirstChild("Humanoid")
humanoid.Died:connect(tp)

On 08, i reccomend something like this:

for i = 5,1,-5 do
txt.Text = "Respawning in:"..(1)
wait(1)

but then again, the fact that it's in starterGui might do something.
