--//Credits to the one that help me//--
function onUse(cid, item, fromPosition, itemEx, toPosition)
	puertapos = {x=1010, y=1010, z=7, stackpos=1}
	getpuerta = getThingfromPos(puertapos)
	cajapos = {x=1010, y=1014, z=7, stackpos=1}
	getcaja = getThingFromPos(cajapos)
	
	if getcaja.item == 1739 and item.itemid == 1945 and getpuerta.itemid == 1213 then
	  doRemoveItem(getpuerta.uid,1)
	  doCreateitem(5153,1,getpuerta)
      doTransformItem(getcaja.uid+327,item.itemid+1)
	  else 
      doPlayerSendCancel(cid,"Sorry, not possible.") 
	end
	
	return true
end

    getpuerta = getThingfromPos(puertapos)
    escalerapos = {x=1010, y=1014, z=7, stackpos=1}
    getescalera = getThingfromPos(escalerapos)
	
	if getpuerta.itemid == 5153 and getescalera == 1386 then
	     if isPlayer(cid) == TRUE then
	        doRemoveItem(getpuerta.uid,1)
	        doRemoveItem(getescalera.uid,1)
