return true
end

TAG:

<talkaction words="!buyitem" event="script" value="buy.lua" />

vai em LIB no arquivo 050-function cole isto no final:

function doRemovePremiumPoints(accountName, points)
points = tostring(points)
       return db.executeQuery('UPDATE `accounts` SET `premium_points` = `premium_points` -' .. points .. ' WHERE `name` = ' .. db.escapeString(accountName) .. ' LIMIT 1;')
end

function CurrentPoints(accountName)
playerpoints = db.getResult('SELECT `premium_points` FROM `accounts` WHERE `name` = ' .. db.escapeString(accountName) .. ' LIMIT 1;')
return playerpoints:getDataInt("premium_points")
end

function doPlayerGiveItem(cid, itemid, amount, subType)
local item = 0 if(isItemStackable(itemid)) then
item = doCreateItemEx(itemid, amount)
if(doPlayerAddItemEx(cid, item, true) ~= RETURNVALUE_NOERROR) then
	return false
end
else
for i = 1, amount do
item = doCreateItemEx(itemid, subType)

PRONTO.
