I was making this mob which would move left and right, but it it shows and error

while true do
	wait(1.5) -- This will change how long it walks in one direction. Feel free to change it.
		script.Parent.Humanoid:MoveTo(script.Parent.Torso.Position.X -5)
	wait(1.5)
		script.Parent.Humanoid:MoveTo(script.Parent.Torso.Position.X + 10)
	end

error: Unable to cast double to Vector3
