Robert,

 Hrrm - A simple solution of course ... and I've spent all this time trying
to figure it out on my own , without asking for help! :)

You've helped me in the past with a few other problems, and you were spot on
each time ..

I envy you, and hope that I am able to become even as half as knowledgeable
as you are..

 Best Regards,

Brian
