function onUse(cid, item, fromPos, item2, toPos)
    if item.itemid == 1945 then
        doRemoveItem(getThingfromPos(stonepos).uid, 1)
        doTransformItem(item.uid,1946)
        addEvent(onTimer7, 30*60*1000) --30minutes
    end
return true
end

    doTransformItem(getThingFromPos({x=33168, y=31669, z=13, stackpos=1}).uid, 1945)--lever pos
    doCreateItem(1484,1,{x=33164, y=31671, z=13})-- Stone pos
