Wow, this worked perfectly. Hate to be a pain, but can you explain how
you went about the logic to achieve this statement or does that just
come with years and years of experience. I mean, to be able to identify

Basically, I watch and learn from others who are more experienced. It's
amazing what one can learn by frequenting these newsgroups, forums,
etc...
