Need help with script ?

I made this ko/wo/credits script but when you reset the first time it doesn't count as a wipe ;/

ranknum = 255
game.Players.PlayerAdded:connect(function(plr)
 if plr:GetRankInGroup(2629411) >= ranknum then
  plr.Chatted:connect(function(msg)
   print("Chat loaded")
   if msg:sub(1, 8):lower() == ":credit" then
    print("part 1")
    local plrindex = msg:sub(9):find(" ")
    if plrindex then
     local subname = (msg:sub(9, 7+plrindex)):lower()
     print(subname)
     local plrs = {}
     if subname == 'me' then
      table.insert(plrs, plr)
      print'ayyy'
     else 
      for i, v in pairs(game.Players:GetPlayers()) do
       if subname == v.Name:sub(1, plrindex-1):lower() then
        print'check'
        table.insert(plrs, v)
       end
      end
     end
     
     if #plrs == 1 then
       print'k'
      pcall(function() plrs[1].leaderstats.Credits.Value = tonumber(msg:sub(plrindex+9)) end)
     end
    end
   end
  end)
 end
end)
