What's wrong with Vector.3.new?

I test it but nothing happens and output does not return me any error or message.

local brick = script.Parent
local cd = script.Parent.ClickDetector
local RD = script.Parent.Parent.Door1.RD
local LD = script.Parent.Parent.Door1.LD
local RDS = script.Parent.Parent.Door1.RDS
local LDS = script.Parent.Parent.Door1.LDS




function onMouseClick(player)
    if not player then return end
        LD.BodyPosition.position = Vector3.new(0, 0, 5)
        LD.BodyPosition.maxForce = Vector3.new(0, 0, 5000)



    end



cd.MouseClick:connect(onMouseClick)
