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

When your firing from the client, never put your player as an argument because ROBLOX automatically does this for you.
