Can someone help me with the scripts of a DialogShop? Please..

Dear, best reader

I'll ask anybody to help me for a DialogShop, mine doesn't work.. So i hope, if you read this and you know how, please send me a script or something.

Thanks already, Greetings, bartjenl

local dialog = script.Parent
dialog.DialogChoiceSelected:connect(function(player, choice)
    -- Check the player has a stats object
    local stats = player:FindFirstChild('leaderstats')
    if not stats then return end
 
    -- And that the stats object contains a gold member
    local gold = stats:FindFirstChild('Gold')
    if not gold then return end
 
    if choice == script.Parent.DialogChoice.ChoiceA then
        if gold.Value >= 5 then -- 5 is the amount of gold you need to purchase this weapon
            game.ReplicatedStorage.Weapon1:Clone().Parent = player.Backpack
            gold.Value = gold.Value - 5 -- subtract the amount of gold you need to purchase
        end
    elseif choice == dialog.DialogChoice.ChoiceB then
        if gold.Value >= 10 then
            game.ReplicatedStorage.Weapon2:Clone().Parent = player.Backpack
            gold.Value = gold.Value - 10
        end
    elseif choice == dialog.DialogChoice.ChoiceC then
        if gold.Value >= 15 then
            game.ReplicatedStorage.Weapon3:Clone().Parent = player.Backpack
            gold.Value = gold.Value - 15
        end
    end
end)
