Does't give points at first kill, but it does on second and so on?

when you kill someone u get points.. but it only give points after the first kill.

here is the script

local Players = game.Players

local Template = Instance.new 'BoolValue'
Template.Name = 'leaderstats'

Instance.new('IntValue', Template).Name = "Kills"
Instance.new('IntValue', Template).Name = "Coins"

local db = 0

Players.PlayerAdded:connect(function(Player)
    wait(1)
    local Stats = Template:Clone()
    Stats.Parent = Player
    Player.CharacterAdded:connect(function(Character)
        local Humanoid = Character:FindFirstChild "Humanoid"
        if Humanoid then
            Humanoid.Died:connect(function()
                for i, Child in pairs(Humanoid:GetChildren()) do
                    if Child:IsA('ObjectValue') and Child.Value and Child.Value:IsA('Player') then
                        local Killer = Child.Value
                        if Killer:FindFirstChild 'leaderstats' and Killer.leaderstats:FindFirstChild "Kills" then
                            if db == 0 then
                            db = db + 1
                            local Kills = Killer.leaderstats.Kills
                            local Coins = Killer.leaderstats.Coins
                            Kills.Value = Kills.Value + 1
                            Coins.Value = Coins.Value + 2
                            wait(1)
                            db = db - 1
                            else return end
                        end
                        return
                    end
                end
            end)
        end
    end)
end)
