Will someone tell me why line 31 keeps erroring out and whats causing it?

I'm making a minigames game but the main script it errors out every time on line 31.... will someone please tell me why? and fix it?

minigames = game.Lighting.minigames:GetChildren()

h = Instance.new("Hint", Workspace)

function removePlate()
	plates = game.Workspace.DissapearingPlates.Plates:GetChildren()
	ranNum1 = math.random(1, #plates)
	ranNum2 = 1
	while ranNum1 == ranNum2 do
		ranNum2 = math.random(1, #plates)
		wait()
	end
	plateChosen = plates(ranNum1)
	plateChosen2 = plates(ranNum2)
	for i = 0, 1, 0.05 do
		plateChosen = plates(ranNum1)
		plateChosen2 = plates(ranNum2)
		for i = 0, 1, 0.05 do
			plateChosen.Transparency = i
			plateChosen2.Transparency = i
			wait()
		end
		plateChosen:Destroy()
		plateChosen2:Destroy()
	end
end

while true do
