The suggestions I received are really great - I am going to try three
different methods and see which one I like best. Also, the info on this
message board is awesome - in the old meaning of the word. A great
resource for people like myself who have good ideas but don't know just
exactly how to do it. Keep up the good work.
Thanx again Barb
