[Ashtar]

well guys i have a simple problem with this scripts, its an action that lets the player using an item to upgrade their weapons attack speed

function onUse(cid, item, fromPosition, itemEx, toPosition)
        if isInArray({2447, 5952, 2400, 7959, 7735, 7405, 8927, 7453, 7958, 8929, 2390, 6259, 8925}, itemEx.itemid) then
            doItemSetAttribute(itemEx.uid, "description", " faster attack speed. It Belongs To ".. getCreatureName(cid) .. ".")
            doItemSetAttribute(itemEx.uid, "attackspeed", 200)
                doPlayerSendTextMessage(cid, 19, "You have upgraded your weapon. Congratulations.")
            doRemoveItem(item.uid)
        else
            doPlayerSendCancel(cid, "Sorry, not possible.")
    end
    
    return true
end
