or you could turn iteration on and put this formula in B1 and copy down to
B40

=IF((B10)*(COUNTIF($B$1:B1,B1)=1),B1,(INT(RAND()* 40+1)))

If you with no matches mean no duplicates and 40 numbers only it won'
really
be random? You can use a simplistic approach and put let's say 1000 from
1-1000 in A1:A1000, then in B1 put =RAND(), copy down to B1000, now select
both columns and sort by column B, then select the first 40 numbers in A
and
copy somewhere else.
