Ellie,
Jean-Pierre's second question here regarding where you want this feature, is right on (hey, that is always the case with Mr. Drolet 🙂 ). Many times the solution to a programming problem is not to find a specific function, it is to do the task differently. One good example is recursive problems. My best advice to you is to be as precise in your question as possible. One can never be too precise but it is very easy to leave information out that is essential to solve the problem. I hope your problem will be solved soon. We are all here to help you out. /Mikael
