IntValue.Changed not working through server script?

This is not working and someone please help!

while wait() do
	local test1 = script.Parent
	test1.Parent.test2.Value.Changed:connect(function(c)
		print(c)
	end)
end

You don't need make a loop to check if changed.

And in line 3 you using IntValue.Value.Changed. But it must be IntValue.Changed like this:

  local test1 = script.Parent
  test1.Parent.test2.Changed:connect(function()
    --Code here
  end)

And i dont know if you test2 is inside of test1. if test2 is inside of test1 then

  local test1 = script.Parent
  test1.test2.Changed:connect(function()
    --Code here
  end)

Or if your test2 isn't inside test1

  local test1 = script.Parent
  test1.Parent.test2.Changed:connect(function()
    --Code here
  end)
