Sorry for the long delay. Covid, world upside down, blah, blah, blah...

Thanks to everyone that replied. Very much appreciated.

Passel - Wow! I tried your code example. I owe you a beer or something for that. I used the resources others pointed me to and your code sample and was able to get this to work as needed. It was amazing how you coded to look exactly like my little drawing. Many thanks.

Just curious - I am assuming I could just as easily code an ASP.net webpage with the same code. Anyone see a reason why not? Thinking about maybe using it for reporting the coordinates I stored from the Application and applying to web reporting of results.

Again. Many thanks for the assist to all.
