I Don't Know Whats Wrong With My Script For a Promocode System?

I Am trying to make a Promocode System and I Have a script that controls all of it but it isn't working

--[[Variable]]--
local PM = script.Parent.PromoMenu
local PC = script.Parent.PromoCodes
local PI = PM.PromoInsert
--[[Scripting]]--
script.Parent.PromocodesOpen.MouseButton1Click:Connect(function()
	if PM.Visible == false then
		PM.Visible = true
	else
		PM.Visible = false
	end
end)

PM.Submit.MouseButton1Click:Connect(function()
	if PI.Text == "C0VID19" then
		print("Work")
	end


	if PI.Text == "Ca3h" then
		print("Work")
	end

	if PI.Text == "M0therL0ad" then
		print("Work")
	end
end)
