    Re: Random Numbers

    You can try this:

    Enter
    =RAND()
    In AA1 and drag across to BN1,
    Then down to BN10,
    So you have a 40 column by 10 row array of random numbers.

    Then, enter this formula anywhere you wish:

    =INDEX(ROW($A1:$A40),RANK(AA1,$AA1:$BN1))

    Now, copy this formula across 6 columns.
    Then, copy down 10 rows.

    This should give you what you're looking for.
    You'll get a new set of numbers with each hit of <F9>.
