This script to give empty cups is not working, there are no errors? [closed]

EDIT: I found out that the ClickDetector doesn't work

So I was scripting for someone, it went fine. But then I had to make this script, I see no error, there is not an error in the output either, I've rewritten the script several times, but it doesn't seem to work

Script:

local debounce = false
for _, model in pairs(script.Parent:GetChildren()) do
    if model:IsA("Model") then
        for _, part in pairs(model:GetChildren()) do
            if part:FindFirstChild("ClickDetector") then
                local storage = game:GetService("ServerStorage")
                part.ClickDetector.MouseClick:connect(function(player)
                    if debounce == false and storage:FindFirstChild(part.Name) then
                        debounce = true
                        local clone = storage:FindFirstChild(part.Name):Clone()
                        clone.Parent = player.Backpack
                        wait()
                        debounce = false
                    end
                end)
            end
        end
    end
end
