Value reaches max instantly instead of gradually?

I'm trying to make it so there's a sort of "Sleep bar" that gradually falls, and to regain it you have to sleep. The bar goes down, but it instantly goes all the way up, instead of slowly rising. Here's the snippet:

    while script.Parent.Occupant ~= nil do
	repeat
		wait(.01)
		prog.Value = prog.Value + 0.000000000001
	until
		prog.Value >= 0.5
		end
	

Do this instead

   if  script.Parent.Occupant then
		for i  = prog.Value, 5 do
		wait()
			prog.Value = tonumber('.' ..i)
		end
	end

that should work

You have a loop through a loop so I would get rid of one of those and make sure it is waiting longer because the way you have it set, it looks like it will fill pretty fast. I would do: local count = 0 while (there is somebody in the bed AND count <= 5) do wait() --To make sure the loop is slowed down count++ --Do something else end
