Hi David,

        Thank you for the explanation.  It's nice to know the difference 
between them.  Since they are equivalent for my use, I went with 
array_key_exists, simply because it makes more sense to me in English. ;)

        Thanks again to everyone.  I got it to work _and_ there are no more
