[Deleted member 141899]

Hello friends, im using TFS 1.1, and im have a problem with my Grizzly Adams script, that the player can open multiples shop windows in same window, if he talks trade many times as him want in the same session...

Here are the part of the grizzly adams trade:

if isInArray({"offer", "trade"}, msg:lower()) then
    if getPlayerRank(cid) >= 2 then
        if getPlayerRank(cid) == 2 or getPlayerRank(cid) == 3 then
            tradeRank = grizzlyAdamsConfig.ranks.huntsMan_rank
        elseif getPlayerRank(cid) == 4 then
            tradeRank = grizzlyAdamsConfig.ranks.bigGameHunter_rank
            setNewLineTable(grizzlyAdamsConfig.ranks.huntsMan_rank, grizzlyAdamsConfig.ranks.bigGameHunter_rank)
        elseif getPlayerRank(cid) == 5 or getPlayerRank(cid) == 6 then
            tradeRank = grizzlyAdamsConfig.ranks.trophyHunter_rank
            setNewLineTable(grizzlyAdamsConfig.ranks.huntsMan_rank, grizzlyAdamsConfig.ranks.bigGameHunter_rank)
            setNewLineTable(grizzlyAdamsConfig.ranks.huntsMan_rank, grizzlyAdamsConfig.ranks.trophyHunter_rank)
        end
        local items = setNewTradeTable(tradeRank)
        local function onBuy(cid, item, subType, amount, ignoreCap, inBackpacks)
            if ignoreCap == false and (player:getFreeCapacity() < getItemWeight(items[item].itemId, amount) or inBackpacks and player:getFreeCap() < (getItemWeight(items[item].itemId, amount) + getItemWeight(1988, 1))) then
                return player:sendTextMessage(MESSAGE_INFO_DESCR, 'You don\'t have enough cap.')
            end
            if items[item].buyPrice then
                player:removeMoney(amount * items[item].buyPrice)
                for i = 1, amount do
                    if inBackpacks then
                        local backpack = doCreateItemEx(1988, 1)
                        doAddContainerItem(backpack, items[item].itemId, amount)
                    else
                        player:addItem(items[item].itemId, amount, true)
                    end
                end
                return player:sendTextMessage(MESSAGE_INFO_DESCR, 'You bought '..amount..'x '..items[item].realName..' for '..items[item].buyPrice * amount..' gold coins.')
            end
            return true
            end
            
        local function onSell(cid, item, subType, amount, ignoreCap, inBackpacks)
            if items[item].sellPrice then
                player:addMoney(items[item].sellPrice * amount)
                player:removeItem(items[item].itemId, amount)
                return player:sendTextMessage(cid, MESSAGE_INFO_DESCR, 'You sold '..amount..'x '..items[item].realName..' for '..items[item].sellPrice * amount..' gold coins.')
            end
            return true
        end
        openShopWindow(cid, tradeRank, onBuy, onSell)
        return npcHandler:say('It\'s my offer.', player)
    else
        return npcHandler:say('You don\'t have any rank.', player)
        end
end

local function setNewTradeTable(table)
    local items = {}
    for _, v in ipairs(table) do
        items[v.id] = {itemId = v.id, buyPrice = v.buy, sellPrice = v.sell, subType = 0, realName = v.name}
    end
    return items
end

local function setNewLineTable(oldTable, newTable)
    for k, v in pairs(oldTable) do
        table.insert(newTable, k, v)
    end
    return true
end

Please help!
