My dialog shop isn't working?(rewrite)

I edited the script but it didn't work so here's the new script( I rewrited the question because I thought that noone will reply still if I edited the old one)

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

local KOs = stats:FindFirstChild('KOs')

)') if not KOs then return end

if choice == script.Parent.DialogChoice.Throwing BOMB then
    if KOs.Value >= 10 then
        game.ReplicatedStorage.Weapon1:Clone().Parent = player.Backpack
        KOs.Value = KOs.Value - 10
    end
elseif choice == dialog.DialogChoice.Darkheart then
    if KOs.Value >= 100 then
        game.ReplicatedStorage.Weapon2:Clone().Parent = player.Backpack
        KOs.Value = KOs.Value - 100
    end
elseif choice == dialog.DialogChoice.Heat seeking missile launcher then
    if KOs.Value >= 500 then
        game.ReplicatedStorage.Weapon3:Clone().Parent = player.Backpack
        KOs.Value = KOs.Value - 500
    end
 elseif choice == dialog.DialogChoice.Red scythe then
    if KOs.Value >= 50 then
        game.ReplicatedStorage.Weapon5:Clone().Parent = player.Backpack
        KOs.Value = KOs.Value - 50
    end
     elseif choice == dialog.DialogChoice.Knife then
    if gold.Value >= 100 then
        game.ReplicatedStorage.Weapon4:Clone().Parent = player.Backpack
        gold.Value = KOs.Value - 100
    end
end

end)

I want a fixed script
