Door error works in studio but not in player and gives no errors when looking in dev console??

This was for my upcoming game and the door wouldnt work in robloxplayer but working in studio?

v = script.Parent.Parent.Value
click = script.Parent.ClickDetector

function wat(player)

        if v.Value == true then
            v.Value = false

            script.Parent.Parent.Door.Transparency = 1
            script.Parent.Parent.Door.CanCollide = false

        elseif v.Value == false then
            script.Parent.Parent.Door.Transparency = 0
            script.Parent.Parent.Door.CanCollide = true

        end
    end

script.Parent.ClickDetector.MouseClick:connect(wat)
