Why won't the GUI show when I touch this part?

I want to make a text appear when this part is touched.

When I touch the part, the text isn’t showing.

I’ve tried to change the c.Parent to game.StarterGui but it hasn’t worked.

Video showcasing problem below.

Script:

Popup = script.Parent.ScreenGui 
Ready = true
function onTouch(hit)
	local h = hit.Parent:FindFirstChild("Humanoid")
	if h ~= nil and Ready == true then
		Ready = false
		local plyr = game.Players:FindFirstChild(h.Parent.Name) 
		local c = Popup:clone()
		c.Parent = plyr.PlayerGui
		wait(3)  
		c:remove() disappear
		wait(1)
		Ready = true
	end
end

What seems to be the problem?

Check if h.Parent is not nil before u check if h is nil. Also try use findfirstchildofclass

local plyr = game.Players:FindFirstChild(h.Parent.Name)

Do this instead, the process will be same.

local plyr = game.Players:GetPlayerFromCharacter(hit.Parent)
