Lua Help with Bonus Exp

[Godshiryu]

Olá. Tenho um servidor e estou com o seguinte problema.
Um player vip ganha 30% mais de exp.
Um player que conquistou o castelo de guerra, ganha 20% mais de exp.
Se um player é vip e conquistou o castelo, ele ganha apenas 30% de exp (que é so vip).
Como fazer pra que ganhe os 50%? (30% vip + 20% castle)
Grato!

Hello, I have a server and I'm with the following problem:
One player vip get 30% more exp than free players.
One player who won the castle of war, get 20% more exp than players without conquest.
If a player are vip, and conquered the castle, he earns only 30% bonus exp (Vip).
What I do to the player win the 50% bonus exp? (30% vip + 20% castle)
Thank you very much!

Sorry for my bad english, I'm from Brazil :S

EDIT:
A action que faz o player ganhar 30% mais exp por ser vip é a seguinte:
The action that causes the player to gain 30% more exp for being vip is as follows:

function onLogin(cid)

local rate = 1.3 -- 30%
local config = {
vip = "Você tem "..((rate - 1)*100).."% de exp a mais agora!",
notvip = "Tornesse vip e ganhe "..((rate - 1)*100).."% a mais de experiencia!",
}

if vip.hasVip(cid) == FALSE then
doPlayerSendTextMessage(cid, MESSAGE_STATUS_CONSOLE_BLUE, config.notvip)
else
doPlayerSetExperienceRate(cid, rate)
doPlayerSendTextMessage(cid, MESSAGE_STATUS_CONSOLE_BLUE, config.vip)
end
return TRUE
end

A Action que faz o player ganhar 20% mais exp pelo castelo é a seguinte:
The Action that makes the player earn 20% more exp the castle is as follows:

dofile("./_woe.lua")

function onLogin(cid)
    Woe.getInfo()
    local Guild_ID = getPlayerGuildId(cid)
    if (Guild_ID == infoLua[2]) and (infoLua[2] ~= 0) then
        doPlayerSetExperienceRate(cid, 1.20)    -- here 
        doPlayerSendTextMessage(cid, MESSAGE_STATUS_CONSOLE_BLUE, "Your guild has won the last War of Emperium, for that reason you have 20% extra experience.")
    end
    return true
end

Ok, I already solved my Problem.
If anyone more need, put this tag on creaturescripts.xml

<event type="login" name="WoeEVipexp" event="script" value="vipecastleexp.lua"/>

and, inside scripts, create vipecastleexp.lua with that inside:

dofile("./_woe.lua")
function onLogin(cid)
    Woe.getInfo()
    local Guild_ID = getPlayerGuildId(cid)
local rate = 1.5 -- 50%
local config = {
vipecastle = "Logo voce tem "..((rate - 1)*100).."% de exp a mais por ter conquistado o castelo e ser vip!",
notviporcastle = "Tornesse vip e ganhe "..((rate - 1)*100).."% a mais de experiencia!",
}

if (vip.hasVip(cid) == TRUE) and (Guild_ID == infoLua[2]) and (infoLua[2] ~= 0) then
doPlayerSetExperienceRate(cid, rate)
doPlayerSendTextMessage(cid, MESSAGE_STATUS_CONSOLE_BLUE, config.vipecastle)
else

end
return TRUE
end

Thanks all anyway!
