local LD = script.Parent.Parent.Door1.LD
local RDS = script.Parent.Parent.Door1.RDS
local LDS = script.Parent.Parent.Door1.LDS
Debounce = false

function onMouseClick(cd)
    if Debounce == false then

        LD.Position = Vector3.new(-27.251,5.37,-4.394) -- I want -4.394 run all the way to 0.476--
