There are far more than 4 numbers between D7900000 and D7920000, and as much as between 3616538624 and 3616669696.
/me Blush I can see that now... I need to do something with my eyes.... :) Finally I understand what I did wrong, and how to solve this ... Thank you for pointing the obvious (not for me :( ) for me :) /me going to crawl now to some place ...
Or what are you calling numbers ? Digits ?
