It is usually a good idea to load in the Limit package in such type of situation. ----------------------------- There are a number of cases where the Limit package gives the wrong answer. I think you still have to proceed with caution. I would only try the approach above if I wasn't satisfied with the result when I didn't use the Limit package. Regards, Ted Ersek
