Help with giving tools from click detector?

Hello. I made a cup part, when it is clicked it should give the player who clicked it a tool. That isn't happening though. The output gives no error either.

Here is the script:

game.Players.LocalPlayer:WaitForChild('Backpack')
function onClicked(plr)
    if plr:GetRankInGroup(3983801) >= 2 then
        local sc1 = game.ServerStorage.Tools.Cups.WhiteCups.SmallEmptyCup:Clone()
        sc1.Parent = game.Players.LocalPlayer.Backpack
        sc1.Name = ('Small Empty Cup')
    end
end

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

Help would be appreciated.

Thanks
