Bye to all,
Congratulations on the idea. the solution is to use the formula that generates values and positions. so much to understand, I attach this link that explains everything: https://www.google.it/url?sa=t&rct=...sg=afqjcng7pgfpcox10pzvnf_bofeizb7a6w&cad=rjaonce you set the correct formula, excel almost by magic will create you everything. citing someone I'm saying "that excel is with you"
I lost a good chance to shut up.
I apologize very much for the inopportune intervention but I am a young attendant of the forum and definitely still very rude.
I had only read the first part of the story and mistakenly thought I was at the end. so I inserted a comment without unfortunately knowing that the good mauro had already made an exceptional file. However, I have reread all previous posts in order to avoid further figurative ones.
years ago I had downloaded from the old site mentioned above, the file in question giving my personal positive appreciation. I therefore take the present opportunity to thank mauro for sharing a great job.
