Hullo David Burrows,

Thank you very much for sharing information with me in coding that makes me understand it logically.

Appreciate your generosity in helping with sample coding.

You are wonderful. I will recommend you to my office other IT Progammers.

I will try out your suggestion and once I got it working I will post it here to share with others who may have encounter similar problems.

I am so glad and happy to meet you here.
