Help with a key door tool?

It works in playtest but not online. I'm not sure what's wrong and output tells me nothing.

bin = script.Parent

function onButton1Down(mouse)

    local hit = mouse.Target
    if (hit == nil) then return end
    if (hit.Name == "SilverDoor2") then
    hit.Transparency = 0.8
    hit.CanCollide = false
    wait(2)
    hit.CanCollide = true
    hit.Transparency = 0

    end
end

function onSelected(mouse)
    print("Action Tool Selected")

    mouse.Button1Down:connect(function() onButton1Down(mouse) end)
end

bin.Selected:connect(onSelected)

Add wait() to the beginning of the script. Scripts that run locally or are based on client-sided objects should be careful to wait that everything has loaded, and for hopperbins this usually fixes it.
