[God Mythera]

Can someone help me make this so i you already have the addon you cant use it again? :s

function onUse(cid, item, fromPosition, itemEx, toPosition)
       
if getPlayerStorageValue(cid,1800) == 10 then
            doCreatureSay(cid, "You already got the second addon", TALKTYPE_ORANGE_1)

    else if getPlayerLevel(cid) >= 8 then
        doCreatureSay(cid, "You received the first addon and the second addon for Pirate Master.", TALKTYPE_ORANGE_1)
            doPlayerAddOutfit(cid, 750, 3)
            doSendMagicEffect(fromPosition, 37)
            doRemoveItem(item.uid)
            setPlayerStorageValue(cid,1800,20)
            return TRUE
        else
                    doCreatureSay(cid, "You must be level 8 to get the second addon", TALKTYPE_ORANGE_1)
        end
end

    if getPlayerStorageValue(cid,1800) == 20 then
        doCreatureSay(cid, "You already got the second addon", TALKTYPE_ORANGE_1)
        return false
    end   
   
    if getPlayerLevel(cid) >= 8 then
        doCreatureSay(cid, "You received the first addon and the second addon for Pirate Master.", TALKTYPE_ORANGE_1)
        doPlayerAddOutfit(cid, 750, 3)
        doSendMagicEffect(fromPosition, 37)
        doRemoveItem(item.uid)
        setPlayerStorageValue(cid,1800,20)
    else
        doCreatureSay(cid, "You must be level 8 to get the second addon", TALKTYPE_ORANGE_1)
    end
    return true
end
