OK Thanks Paul. Been trying since my message and I couldn't come up with the solution. So now I know, at times, there is No formula that fits all instances. And we need to validate the query.

I'm deeply grateful Paul, Have yourself a great evening

P.S.: by the way, I'll be taking a course soon, for beginners. I know I'm more advance than beginners, but I need to fill up grey areas, cause I've learned by analyzing, but missing some key basic component.
