Broken drop system

[Captain Spark]

So basically, thanks to Acecool on this one, I've had this working chatcommands code, and I setup a money drop chatcommand feature, which worked the whole day.
This is the error I get.

[ERROR] gamemodes/example/entities/entities/money_smallgold/init.lua:27: attempt
 to compare number with string
  1. unknown - gamemodes/example/entities/entities/money_smallgold/init.lua:27
   2. unknown - lua/includes/modules/concommand.lua:69

If you wish to look at all the code, here's the pastebin: [url]http://pastebin.com/kYG5Jrx6[/url]

        function Player:AddMoney(num)
                self:SetMoney(tonumber(self:GetMoney())+tonumber(num))
        end
        function Player:RemoveMoney(num)
                self:SetMoney(tonumber(self:GetMoney())-tonumber(num))
        end

It seems to work even though I'm not sure it came from your fix. My gamemode seems to break and restart working every now and then, and I have no clue why. Anyway, thanks.
