Whats wrong with my code?

function endProgram()
	if game.Workspace:findFirstChild("Program") ~= nil then
		running = false
		makeGui("Venterion://PROGRAMS//ENDING_PROGRAM//",2.5)a
		for _,v in pairs(game.Workspace.Program:GetChildren()) do
			if v:IsA("Part") or v:IsA("TrussPart") or v:IsA("Wedge") then
				x = Instance.new("SelectionBox",v)
				x.Color = BrickColor.new("Bright red")
				x.Adornee = v
				wait()
				v.Transparency = 1
				wait()
			end
		end
		game.Workspace.Program:Destroy()
		makeGui("Venterion://PROGRAMS//PROGRAM_ENDED//",2.5)
		running = false
		return running
	end
end

it says the for is wrong, what is wrong?
