If you'll discover the answer easily, following a link you can find in each one of my posts, I'll think about erasing this puzzle. 

I'm sure you missed this post...in any case I knew it was going to happen sooner or later.
It was nearly impossible to solve it and that's why I invited Robert to join Autopuzzles and share more info on his creation.
