Solved How to change Item Unique or Action Id with function

[whitevo]

Cannot find working method for changing item unique ID
I am using TFS 1.0 Client 10.41

function onUse(cid, item, fromPosition, itemEx, toPosition)
    if item.uid == 1003 then   
        local p = {x=527,y=768,z=8} -- TP coordinates
        doTeleportThing(cid,p)
        doItemSetAttribute(uid, 1004)
    elseif item.uid == 1004 then   
        local p = {x=527,y=768,z=9} -- TP coordinates
        doTeleportThing(cid,p)
        doItemSetAttribute(uid, 1003)
    else
    return false
    end
end

here is my latest test.. I tried lot of different lines, none of them work, some give errors, some nothing. Anyone knows what is the correct method?

function onUse(cid, item, fromPosition, itemEx, toPosition)
    Player(cid):teleportTo(Position(527, 768, 9))
    Item(item.uid):setAttribute(ITEM_ATTRIBUTE_UNIQUEID, item.uid == 1003 and 1004 or 1003)
    return true
end
