How to update or refresh a local variable?

I made a script that moves a block to the player torso's X position. It moves to the position, but only to the original one (where the player spawned). I looked it up and came up with results of update on change and all, but once I put one of my local variables in it, the other local variable (which uses the first variable) underlined blue. Am I doing it wrong? Is there an easier solution? Here is my script

repeat
wait(2.5)
local victim = workspace:FindFirstChild("Player")
local location = victim.Torso.Position
print(location.X)
wait(0.0001)
	repeat
		wait(0.000001)
		repeat
			wait(0.000001)
			if script.Parent.Position.X ~= location.X then
				if location.X > script.Parent.Position.X then
					print("bigger")
					script.Parent.Position = script.Parent.Position + Vector3.new(1,0,0)
				elseif location.X < script.Parent.Position.X then
					print("smaller")
					script.Parent.Position = script.Parent.Position - Vector3.new(1,0,0)
				elseif location.X == script.Parent.Position.X then
					print("found")
				end
			end
		until script.Parent.Position.X == location.X
	until 9 + 10 == 21 -- this is necessary for the fact that it will change once i get the variable situation sorted out
until 9 + 10 == 21 --refer to the above comment

Please help!!! Thank you!!!
