[SOLVED] My npc isnt moving like it should be?

I was programming an npc movement script of my game but the npc wont move, there are no errors in the output just my script isnt working. The npc is a R15 type model

local humanoid =  script.Parent.Humanoid

while true do
	humanoid:MoveTo(Vector3.new(50,0,0))
	humanoid.MoveToFinished:Wait()
	humanoid:MoveTo(Vector3.new(0,0,0))
	humanoid.MoveToFinished:Wait()
end
