This might seem stupid, but how would I move this frame upward in a loop?

So I'm trying to make a credit Gui and I need this frame to move upward so I put this script into it:

while true do
	wait(0.1)
	script.Parent.Position.Y.Offset = script.Parent.Position.Y.Offset + 1
end

Its not working for some reason, my guess is that offset is something else but i dont really have a clue, can you help me?
