I did it in 5 minutes... I didn't add comments cause i believe comments deserve money ! (ah wait, maybe i'm just too lazy to explain) _________________ The Shning, more useful than The Useful Site Posted: 03-20-2003 02:10 PM M0nKeY - Remember - Joined: 09 Feb 2002 Posts: 1235 I was using a loop to compare 6 seperate variables, it was messy and crappy. This is way better. Is there a way that it can select more than 10 numbers though? LIke 01,02,13,07,21,05 Thanks. Posted: 03-20-2003 05:16 PM Shn R.I.P.

I bet you can highly optimize this, but i've got no idea how. It'll be 200 euros. I accept checks, credit cards, cash.
