You can use =RANDBETWEEN(1,36), to use the function

Ok that seemed to work but what do I do about the duplicate numbers in the columns and rows?

Hi Paul:
This is how I have done in the past (I wouldn't be surprised that there is a better way), if I wanted 36 unique numbers selected randomly, I would ask for say 100 random numbers, then I would filter this list to retain only unique numbers. Plese post back whether it works for you!

Suppose you wanted a 6x6 array or random numbers between 1 and 36 inclusive...

1. Enter the series 1 through 36 in A1:A36.
2. Enter the formula, =RAND(), in B1:B36.
3. Enter the values, {0,1,2,3,4,5}, in E1:J1.
4. Enter the values, {1;7;13;19;25;31}, in D2:D7.
5. Enter the formula, =INDEX(\$A:\$A,\$D2+E\$1), into
E2, copy right to cell J2, and copy down to cell
J7.

Cells E2:J7 now contains your 6x6 array of random
values. Resort A:B based on column B when you
need a new set of random values.
