Raul, Your reply is exactly what I wanted! I just thought my explanation had been confusing so I gave more details. Your functions are both fine and after I have a chance to ponder a while, I'll let you know what my "elementary" take on it is. Thanks. I have lots of old pictures and I don't know when they were taken. When I don't know who someone is, knowing the old relatives ages helps to elimate ones who weren''t alive at the time of the picture. (Probably too much information) Thanks again. Linda

But your following description seems to me to be claiming that what I implemented *is* what you want. So I am a bit confused now. Is there anything you can do to help me resolve this implied contradiction?
