Why is my script not finding a GUI in PlayerGui? Part 2...

This script that I made is supposed to tween a Frame in a GUI when you touch a brick, but I keep getting an error.

(This script works in studio, but not in game!)

function onTouched(m)
	local debounce = true
	local p = m.Parent:findFirstChild("Humanoid")
	if p ~= nil then
		if debounce == true then
			debounce = false
			p.WalkSpeed = 0
			local name = p.Parent.Name
			local player = game:GetService("Players"):WaitForChild(name)
				player.PlayerGui:WaitForChild("Teleport").Frame:TweenPosition
				(UDim2.new(0,0,0,0), "Out", "Linear", 1)
			wait(2)
			p.Torso.CFrame = script.Parent.b.CFrame
			wait(1)
				player.PlayerGui:WaitForChild("Teleport").Frame:TweenPosition
				(UDim2.new(0,0,-2,0), "Out", "Linear", 1)
			wait(0.1)
			debounce = true
			wait(1)
			p.WalkSpeed = 16
		end
	end
end
script.Parent.boi.Touched:connect(onTouched)

I asked this before and someone answered, but the script wouldn't have worked with the full script, so here it is...

You’re using lots of deprecated code.

On line 3, change findFirstChild to FindFirstChild

On line 4, remove the ~= nil part as it’s unimportant and only extends your if statement

On line 24, change connect to Connect

Another error is you’re trying to modify GUI from the server. I gave you a previous answer, just fit the FireClient() there somewhere in your script.
