Hi everyone!

I'm trying to write my first AddOn about showing my total money and latency in game,
But I notice that the total amount and latency only updated after input "/reload" in game now,

here is my code,

local m = CreateFrame("Frame", nil, UIParent);
      m:SetPoint("BOTTOMRIGHT", UIParent, "BOTTOMRIGHT", -88, 6);
      m:SetWidth(80);
      m:SetHeight(10);
      m:RegisterEvent("PLAYER_MONEY");
      m:RegisterEvent("PLAYER_ENTERING_WORLD");

local Getmoney = GetMoney();
      money = m:CreateFontString(Getmoney, nil, nil);
      money:SetAllPoints(m);
      money:SetFont(STANDARD_TEXT_FONT, 12, "OUTLINE");
      money:SetJustifyH("LEFT");
      money:SetTextColor( 1, 1, 1 );
      money:SetFormattedText(("%d|cffFFD700g|r ".." %d|cffB5B5B5s|r ".." %d|cffCD853Fc|r"):format(Getmoney /10000, (Getmoney / 100) % 100, Getmoney % 100));

local bandwidthIn, bandwidthOut, latencyHome, latencyWorld = GetNetStats();

  local l = CreateFrame("Frame", nil, UIParent)
        l:SetPoint("BOTTOMRIGHT", UIParent, "BOTTOMRIGHT", -21, 6)
        l:SetWidth(80)
        l:SetHeight(10)
        l:RegisterEvent("PLAYER_ENTERING_WORLD")

        latency = l:CreateFontString(latency, nil, nil)
        latency:SetAllPoints(l)
        latency:SetFont(STANDARD_TEXT_FONT, 12, "OUTLINE")

        --latency:SetShadowOffset(1, -1)
        --latency:SetShadowColor(0, 0, 0, 1)

        latency:SetJustifyH("RIGHT")
        latency:SetTextColor( 1, 1, 1 )
        latency:SetFormattedText(latencyHome.."/"..latencyWorld.."|cff87CEEB ms")

I'm new to Lua, learn all above codes from wowwiki and blizz source codes.
