My H locked his cell phone so i can't check to see who called him. Does anyone know the formula in excel that i can do to find all the combination possibilities that could occur between 0-9 that would result in a 4 digit code. I know there will be A LOT. But i have nothing but time.<P><BR>Thank you<p>[This message has been edited by Maturing (edited August 01, 2000).]

i posted to bring this to the top - anyone w/ excel knowledge please answer

If my math is correct (it has been a loooong time!) There are 6561 possible combinations. As for the formula, you do not really need that. I would suggest you format 13 columns as text (not general). Across the top cells type:<BR>0000 0500 1000 1500 2000 ... 6500<BR>Then highlight those numbers, place your cursor to the bottom right of the highlighted cells (you will get a small black cross) Then left click and pull down for 500 rows. Print it out.<P>You should only use this to cross off the numbers you try. An old hackers secret, never start at 0000 and work you way up. Try Social Security numbers, birthdays, combinations of important dates, etc. If that doesn't work, reverse the numbers. This will reveal the numbers 7 out of 10 times. If this doesn't work, then try easily remembered numbers. 6969 seems to be a common number (don't ask). also 0000 or 1111 or 2222 or 1212 or 1234. You get the idea. Cross off each attempt. Only as a last resort start at the beginning.
