I'm making a money remote event that gives a player money. It doesn't work, why?

So, I have a RemoteEvent called AddMoney. I keep on getting this error: 10:01:43.603 - Value is not a valid member of Player. I don't know if I have something wrong with the ServerScript or the LocalScript, but I need to fix this. Any help?

ServerScript:

game.ReplicatedStorage.Events.AddMoney.OnServerEvent:Connect(function(player, cash)
    for _,v in pairs(game.ServerStorage.PlayerMoney:GetChildren()) do
        if v.Name == player.Name then
            v.Value = v.Value + cash.Value
        end
    end
end)

LocalScript:

local events = game:GetService("ReplicatedStorage").Events
local addImage = events.AddImage
local addMoney = events.AddMoney

local player = game.Players.LocalPlayer
local gui = player.PlayerGui.ShipmentGui.ShipmentFrame

local debounce = false
for _,v in pairs(gui.ShipmentButtons:GetChildren()) do
    if (v:IsA("TextButton")) then
        local value = v.ItemUnlocked
        if (value) then
            v.MouseButton1Click:Connect(function()
                if (value.Value == true) then
                    if (debounce == false) then
                        debounce = true
                        addMoney:FireServer(player, v.Money)

                        wait(.5)
                        gui.Visible = false

                        wait(20)
                        debounce = false
                    end
                end
            end)
        end
    end
end

If you're confused with the "PlayerMoney", that is just a value stored in the server so that it can't be hacked by any clients
