I did not explain my self well. What I am doing is genarating random
sequences numbers from 1 to 100. When I use the formula randbetween(1,100) in
'A2' and copy to range 'D26', it did give me duplicate numbers.

Say your data is in column B from B2 thru B1000 and we want to sample 100 of
these values with no repeats.

In A2 thru A1000 enter:
=rand()

In E2, enter:
=OFFSET($B$2,MATCH(LARGE($A$2:$A$1000,ROW()),$A$2: $A$1000,0),0)
and copy down thru E101

I am trying to extract a random sample of 100 numbers .
The problem that I'm having is that the sample keeps coming up with
duplicate numbers.

Can anyone tell me how I can eliminate these duplicates?

Any help would be appreciated
