Janet, ya know...that's the kinda response I really appreciate seeing...you do have a talent for 'mining' and finding gold...this answer is far more valuable than a "http" for a reference site or referral to the archives...we all benefit from the info even if it is just a review for most reading it... ...it may seem lazy on my part, but replies with referrals elsewhere drain what lil energy I may have at the time and I tend to 'give up'. jus one opinion... :-) Gail Vass
